Stroke following coronary interventions is a devastating and most dreaded complication with significant morbidity and mortality. Various factors have been ascribed for this complication including the ...technical errors. We hereby describe such a patient who presented to us with the diagnosis of acute coronary syndrome and underwent percutaneous coronary intervention (PCI) but unfortunately developed left sided hemiparesis due to ischaemic stroke (right middle cerebral artery). She was managed as per the standard treatment protocols for acute coronary syndrome and later on for ischaemic stroke which she nicely responded to and was discharged in a haemodynamically stable condition. On follow-up after 15 days, she was totally symptom-free. We will discuss all the possible preventive and treatment measures for this rare complication of (PCI).
Using 57.2 pb−1 of data collected with the CLEO-c detector at the ψ(3770) resonance, we measure absolute branching fractions for three D0 and two D+ Cabibbo-allowed hadronic decay modes, and the ...cross section for e+e− → D at Ecm 3.77 GeV. We report preliminary measurements of branching fractions (D0 → K−π+) (3.92 ± 0.08 ± 0.23)%, (D0 → K−π+π0) (14.3 ± 0.3 ± 1.0)%, (D0 → K−π+π+π−) (8.1 ± 0.2 ± 0.9)%, (D+ → K−π+π+) (9.8 ± 0.4 ± 0.8)%, and (D+ → KS0π+) (1.61 ± 0.08 ± 0.15)%. and the cross sections σ(e+e− → D ) (6.06 ± 0.13 ± 0.22) nb.
In this Letter, we describe a search for lepton flavor violation (LFV) in the bottomonium system. We search for leptonic decays Upsilon(nS)-->mutau (n=1, 2, and 3) using the data collected with the ...CLEO III detector. We identify the tau lepton using its leptonic decay nu_{tau}nuover _{e}e and utilize multidimensional likelihood fitting with probability density function shapes measured from independent data samples. We report our estimates of 95% C.L. upper limits on LFV branching fractions of Upsilon mesons. We interpret our results in terms of the exclusion plot for the energy scale of a hypothetical new interaction versus its effective LFV coupling in the framework of effective field theory.
We present measurements of the differential cross section d sigma/dp(T)(gamma) for the inclusive production of a photon in association with a b-quark jet for photons with rapidities vertical bar ...y(gamma)vertical bar < 1.0 and 30 < p(T)(gamma) < 300 GeV, as well as for photons with 1.5 < vertical bar y(gamma)vertical bar < 2.5 and 30 < p(T)(gamma) < 200 GeV, where p(T)(gamma) is the photon transverse momentum. The b-quark jets are required to have p(T) > 15 GeV and rapidity vertical bar Y-jet vertical bar < 1.5. The results are based on data corresponding to an integrated luminosity of 8.7 fb(-1), recorded with the DO detector at the Fermilab Tevatron p<(p)over bar>) Collider at root s = 1.96 TeV. The measured cross sections are compared with next-to-leading order perturbative QCD calculations using different sets of parton distribution functions as well as to predictions based on the k(T)-factorization QCD approach, and those from the SHERPA and PYTHIA Monte Carlo event generators.
The decay {psi}(2S){yields}{eta}J/{psi} is used to measure, for the first time, all prominent {eta}-meson branching fractions with the same experiment in the same dataset, thereby providing a ...consistent treatment of systematics across branching fractions. We present results for {eta} decays to {gamma}{gamma}, {pi}{sup +}{pi}{sup -}{pi}{sup 0}, 3{pi}{sup 0}, {pi}{sup +}{pi}{sup -}{gamma} and e{sup +}e{sup -}{gamma}, accounting for 99.9% of all {eta} decays. The precision of several of the branching fractions and their ratios is improved. Two channels, {pi}{sup +}{pi}{sup -}{gamma} and e{sup +}e{sup -}{gamma}, show results that differ at the level of three standard deviations from those previously determined.
We measure the mass of the {eta} meson using {psi}(2S){yields}{eta}J/{psi} events acquired with the CLEO-c detector operating at the CESR e{sup +}e{sup -} collider. Using the four decay modes ...{eta}{yields}{gamma}{gamma}, 3{pi}{sup 0}, {pi}{sup +}{pi}{sup -}{pi}{sup 0}, and {pi}{sup +}{pi}{sup -}{gamma}, we find M{sub {eta}}=547.785{+-}0.017{+-}0.057 MeV, in which the first uncertainty is statistical and the second systematic. This result has an uncertainty comparable to the two most precise previous measurements and is consistent with that of NA48, but is inconsistent at the level of 6.5{sigma} with the much smaller mass obtained by GEM.
