The Andro-Gin unit used in combined treatment of 78 patients with chronic prostatitis (CP) and 16 women with chronic interstitial cystitis with inflammation in the internal genitalia (56.5% of the ...patients had sexual and spermatogenesis disorders) employed effects of simultaneous exposure to local magnetic field, electrostimulation of the small pelvis organs and prostate with introduction of contact rectal electrode, neurostimulation of pathogenic zones, low-intensity laser and light-diode radiator and color impulse therapy. Control group consisted of 85 patients with CP who received conventional physiotherapy. The comparative analysis has shown high efficiency of the unit Andro-Gin in the treatment of CP and its complications. Laboratory and clinical convalescence and persistent remission was registered in 98% of the patients of the study group. Combined treatment using Andro-Gin is twice more effective than other treatments.
We report a study of the \(e^{+}e^{-} \to D^{+} D^{-} \pi^{+} \pi^{-}\) process using \(e^{+}e^{-}\) collision data samples with an integrated luminosity of \(2.5\,\rm{fb}^{-1}\) at center-of-mass ...energies from 4.36 to \(4.60 \rm{GeV}\), collected with the BESIII detector at the BEPCII storage ring. The \(D_{1}(2420)^+\) is observed in the \(D^{+} \pi^{+} \pi^{-}\) mass spectrum. The mass and width of the \(D_{1}(2420)^+\) are measured to be \((2427.2\pm 1.0_{\rm stat.}\pm 1.2_{\rm syst.}) \rm{MeV}/c^2\) and \((23.2\pm 2.3_{\rm stat.} \pm2.3_{\rm syst.}) \rm{MeV}\), respectively. The first errors are statistical and the second ones are systematic. In addition, the Born cross sections of the \(e^{+}e^{-} \to D_{1}(2420)^+D^- + c.c. \to D^{+} D^{-} \pi^{+} \pi^{-}\) and \(e^{+}e^{-} \to \psi(3770) \pi^{+} \pi^{-} \to D^{+} D^{-} \pi^{+} \pi^{-}\) processes are measured as a function of the center-of-mass energy.
Using a sample of \((448.1\pm2.9)\times10^6\) \(\psi(3686)\) events collected with the BESIII detector, we perform the first partial wave analysis of \(\psi(3686)\rightarrow K^+K^-\eta\). In addition ...to the well established states, \(\phi(1020)\), \(\phi(1680)\), and \(K_3^*(1780)\), contributions from \(X(1750)\), \(\rho(2150)\), \(\rho_3(2250)\), and \(K^*_2(1980)\) are also observed. The \(X(1750)\) state is determined to be a \(1^{--}\) resonance. The simultaneous observation of the \(\phi(1680)\) and \(X(1750)\) indicates that the \(X(1750)\), with previous observations in photoproduction, is distinct from the \(\phi(1680)\). The masses, widths, branching fractions of \(\psi(3686)\rightarrow K^+K^-\eta\) and the intermediate resonances are also measured.
Using a 2.93 fb\(^{-1}\) data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to \((8296\pm31\pm64)\times10^3 D^+D^-\) ...pairs, we search for the baryon and lepton number violating decays \(D^+\to\bar\Lambda(\bar\Sigma^0)e^+\) and \(D^+\to\Lambda(\Sigma^0)e^+\). No obvious signals are found with the current statistics and upper limits on the branching fractions of these four decays are set at the level of \(10^{-6}\) at 90% confidence level.
The differential cross section for the production of charged hadrons with high transverse momenta in the scattering of 160 GeV/c muons off nucleons at low photon virtualities has been measured at ...the COMPASS experiment at CERN. The results, which cover transverse momenta from 1.1 GeV/c to 3.6 GeV/c , are compared to a perturbative quantum chromodynamics (pQCD) calculation, in order to evaluate the applicability of pQCD to this process in the kinematic domain of the experiment. The shape of the calculated differential cross section as a function of transverse momentum is found to be in good agreement with the experimental data, but the absolute scale is underestimated by next-to-leading order pQCD. The inclusion of all-order resummation of large logarithmic threshold corrections reduces the discrepancy from a factor of 3 to 4 to a factor of 2. The dependence of the cross section on the pseudorapidity and on the virtual photon energy fraction is investigated. Finally the dependence on the charge of the hadrons is discussed.
The process of \(e^+e^- \rightarrow p\bar{p}\) is studied at 22 center-of-mass energy points (\(\sqrt{s}\)) from 2.00 to 3.08 GeV, exploiting 688.5~pb\(^{-1}\) of data collected with the BESIII ...detector operating at the BEPCII collider. The Born cross section~(\(\sigma_{p\bar{p}}\)) of \(e^+e^- \rightarrow p\bar{p}\) is measured with the energy-scan technique and it is found to be consistent with previously published data, but with much improved accuracy. In addition, the electromagnetic form-factor ratio (\(|G_{E}/G_{M}|\)) and the value of the effective (\(|G_{\rm{eff}}|\)), electric (\(|G_E|\)) and magnetic (\(|G_M|\)) form factors are measured by studying the helicity angle of the proton at 16 center-of-mass energy points. \(|G_{E}/G_{M}|\) and \(|G_M|\) are determined with high accuracy, providing uncertainties comparable to data in the space-like region, and \(|G_E|\) is measured for the first time. We reach unprecedented accuracy, and precision results in the time-like region provide information to improve our understanding of the proton inner structure and to test theoretical models which depend on non-perturbative Quantum Chromodynamics.
Using a total of 11.0 fb\(^{-1}\) of \(e^{+}e^{-}\) collision data with center-of-mass energies between 4.009 GeV and 4.6 GeV and collected with the BESIII detector at BEPCII, we measure fifteen ...exclusive cross sections and effective form factors for the process \(e^{+}e^{-}\rightarrow\Xi^{-}\bar\Xi^{+}\) by means of a single baryon-tag method. After performing a fit to the dressed cross section of \(e^{+}e^{-}\rightarrow\Xi^{-}\bar\Xi^{+}\), no significant \(\psi(4230)\) or \(\psi(4260)\) resonance is observed in the \(\Xi^{-}\bar\Xi^{+}\) final states, and upper limits at the 90\% confidence level on \(\Gamma_{ee}\mathcal{B}\) for the processes \(\psi(4230)\)/\(\psi(4260)\rightarrow\Xi^{-}\bar\Xi^{+}\) are determined. In addition, an excited \(\Xi\) baryon at 1820 MeV/\(c^{2}\) is observed with a statistical significance of 6.2 \(\sim\) 6.5\(\sigma\) by including the systematic uncertainty, and the mass and width are measured to be \(M = (1825.5 \pm 4.7 \pm 4.7)\)~MeV/\(c^{2}\) and \(\Gamma = (17.0 \pm 15.0 \pm 7.9)\)~MeV, which confirms the existence of the \(J^{P}=\frac{3}{2}^{-}\) state \(\Xi(1820)\).
The cross section of the process \(e^+e^-\to\pi^+\pi^-\pi^0\) is measured with a precision of 1.6% to 25% in the energy range between \(0.7\) and 3.0 GeV using the Initial State Radiation method. A ...data set with an integrated luminosity of \(2.93\)fb\(^{-1}\) taken at the center-of-mass energy of \(\sqrt{s}=3.773\)GeV with the BESIII detector at the BEPCII collider is used. The product branching fractions for \(\omega\), \(\phi\), \(\omega(1420)\), and \(\omega(1650)\) are measured to be \(\mathcal{B}(\omega\to e^+e^-) \times \mathcal{B}(\omega \to \pi^+\pi^-\pi^0)=(6.94\pm0.08\pm0.16) \times 10^{-5}\), \(\mathcal{B}(\phi\to e^+e^-) \times \mathcal{B}(\phi\to\pi^+\pi^-\pi^0) = (4.20\pm0.08\pm0.19) \times 10^{-5}\), \(\mathcal{B}(\omega(1420)\to e^+e^-) \times \mathcal{B}(\omega(1420) \to \pi^+\pi^-\pi^0) = (0.84\pm0.09\pm0.09) \times 10^{-6}\), and \(\mathcal{B}(\omega(1650) \to e^+e^) \times \mathcal{B}(\omega(1650)\to \pi^+\pi^-\pi^0) = (1.14\pm0.15\pm0.15)\times10^{-6}\), respectively. The branching fraction \(\mathcal{B}(J/\psi\to \pi^+\pi^-\pi^0)\) is measured to be \((2.188 \pm 0.024 \pm 0.024 \pm0.040 (\Gamma_{ee}^{J/\psi}))\%\), where \(\Gamma_{ee}^{J/\psi}\) is the dileptonic width of \(J/\psi\). The first errors are of statistical, the second and third ones of systematic nature.
The cross section of the process \(e^+e^- \rightarrow \eta'J/\psi\) is measured at center-of-mass energies from \(\sqrt{s} =\) 4.178 to 4.600 GeV using data samples corresponding to a total ...integrated luminosity of 11 fb\(^{-1}\) collected with the BESIII detector operating at the BEPCII storage ring. The dependence of the cross section on \(\sqrt{s}\) shows an enhancement around \(4.2\) GeV. While the shape of the cross section cannot be fully explained with a single \(\psi(4160)\) or \(\psi(4260)\) state, a coherent sum of the two states does provide a reasonable description of the data.
Using a sample of \(1.31\times10^{9} ~J/\psi\) events collected with the BESIII detector, we perform a study of \(J/\psi\to\gamma K\bar{K}\eta'\). The \(X(2370)\) is observed in the \(K\bar{K}\eta'\) ...invariant-mass distribution with a statistical significance of 8.3\(\sigma\). Its resonance parameters are measured to be \(M = 2341.6 \pm 6.5\text{(stat.)} \pm 5.7\text{(syst.)}\)~MeV/\(c^{2}\) and \(\Gamma = 117 \pm 10 \text{(stat.)} \pm 8 \text{(syst.)}\)~MeV. The product branching fractions for \(J/\psi\to \gamma X(2370), X(2370) \to K^{+} K^{-}\eta'\) and \(J/\psi\to \gamma X(2370), X(2370) \to K_{S}^{0} K_{S}^{0}\eta'\) are determined to be \((1.79 \pm 0.23 \text{(stat.)} \pm 0.65 \text{(syst.)}) \times 10^{-5}\) and \((1.18 \pm 0.32\ text{(stat.)} \pm 0.39 \text{(syst.)}) \times 10^{-5}\), respectively. No evident signal for the \(X(2120)\) is observed in the \(K\bar{K}\eta'\) invariant-mass distribution. The upper limits for the product branching fractions of \(\mathcal{B}(J/\psi \to \gamma X(2120)\to\gamma K^{+} K^{-} \eta')\) and \(\mathcal{B}(J/\psi\to\gamma X(2120)\to\gamma K_{S}^{0} K_{S}^{0} \eta')\) are determined to be \(1.49\times10^{-5}\) and \(6.38\times10^{-6}\) at the 90% confidence level, respectively.
