This report details the capabilities of LHCb and its upgrades towards the study of kaons and hyperons. The analyses performed so far are reviewed, elaborating on the prospects for some key ...decay channels, while proposing some new measurements in LHCb to expand its strangeness research program.
A method is proposed to measure the photon polarisation parameter
in
transitions using an amplitude analysis of
decays. Simplified models of the
system are used to simulate
and
decays, validate the ...amplitude analysis method, and demonstrate the feasibility of a measurement of the
parameter irrespective of the model parameters. Similar sensitivities to
are obtained with both the charged and neutral hadronic systems. In the absence of any background and distortion due to experimental effects, the statistical uncertainty expected from an analysis of
decays in an LHCb data set corresponding to an integrated luminosity of 9
is estimated to be 0.009. A similar measurement using
decays in a Belle II data sample corresponding to an integrated luminosity of 5
would lead to a statistical uncertainty of 0.018.
A method is proposed to measure the photon polarisation parameter Formula omitted in Formula omitted transitions using an amplitude analysis of Formula omitted decays. Simplified models of the ...Formula omitted system are used to simulate Formula omitted and Formula omitted decays, validate the amplitude analysis method, and demonstrate the feasibility of a measurement of the Formula omitted parameter irrespective of the model parameters. Similar sensitivities to Formula omitted are obtained with both the charged and neutral hadronic systems. In the absence of any background and distortion due to experimental effects, the statistical uncertainty expected from an analysis of Formula omitted decays in an LHCb data set corresponding to an integrated luminosity of 9 Formula omitted is estimated to be 0.009. A similar measurement using Formula omitted decays in a Belle II data sample corresponding to an integrated luminosity of 5 Formula omitted would lead to a statistical uncertainty of 0.018.
Patients infected with the human immunodeficiency virus (HIV) have an increased cardiovascular risk. Although initially this increased risk was attributed to metabolic alterations associated with ...antiretroviral treatment, in recent years, the attention has been focused on the HIV disease itself. Inflammation, immune system activation, and endothelial dysfunction facilitated by HIV infection have been identified as key factors in the development and progression of atherosclerosis. In this review, we describe the epidemiology and pathogenesis of cardiovascular disease in patients with HIV infection and summarize the latest knowledge on the relationship between traditional and novel inflammatory, immune activation, and endothelial dysfunction biomarkers on the cardiovascular risk associated with HIV infection.
A method is proposed to measure the photon polarisation parameter $\lambda _{\gamma }$ in ${{b}} \!\rightarrow {s} {\gamma } $ transitions using an amplitude analysis of $B\!\rightarrow K\pi \pi ...{\gamma } $ decays. Simplified models of the ${K} {\pi } {\pi } $ system are used to simulate ${{{B} ^+}} \!\rightarrow {{K} ^+} {{\pi } ^-} {{\pi } ^+} {\gamma } $ and ${{B} ^0} \!\rightarrow {{K} ^+} {{\pi } ^-} {{\pi } ^0} {\gamma } $ decays, validate the amplitude analysis method, and demonstrate the feasibility of a measurement of the $\lambda _{\gamma }$ parameter irrespective of the model parameters. Similar sensitivities to $\lambda _{\gamma }$ are obtained with both the charged and neutral hadronic systems. In the absence of any background and distortion due to experimental effects, the statistical uncertainty expected from an analysis of ${{{B} ^+}} \!\rightarrow {{K} ^+} {{\pi } ^-} {{\pi } ^+} {\gamma } $ decays in an LHCb data set corresponding to an integrated luminosity of 9 $\,\hbox {fb}^{-1}$ is estimated to be 0.009. A similar measurement using ${{B} ^0} \!\rightarrow {{K} ^+} {{\pi } ^-} {{\pi } ^0} {\gamma } $ decays in a Belle II data sample corresponding to an integrated luminosity of 5 $\hbox {\,ab}^{-1}$ would lead to a statistical uncertainty of 0.018.

The gUSE (Grid User Support Environment) framework allows to create, store and distribute application workflows. This workflow architecture includes a wide variety of payload execution operations, ...such as loops, conditional execution of jobs and combination of output. These complex multi-job workflows can easily be created and modified by application developers through the WS-PGRADE portal. The portal also allows end users to download and use existing workflows, as well as executing them. The DIRAC framework for distributed computing, a complete Grid solution for a community of users needing access to distributed computing resources, has been integrated into the gUSE/WS-PGRADE system. This integration allows the execution of gUSE workflows in a distributed computing environment, thus greatly expanding the capability of the portal to several Grids and Cloud Computing facilities. The main features and possibilities of the gUSE/WS-PGRADE-DIRAC system, as well as the benefits for users, will be outlined and discussed.
Acute spinal cord injury leaves patients severely impaired and generates high levels of psychological distress among them and their families, which can cause a less active role in rehabilitation, ...worse functional recovery, and less perceived satisfaction with the results. Additionally, rehabilitation professionals who deal with this psychological distress could ultimately experience higher stress and more risk of burnout. This article presents the study protocol of the ESPELMA project, aimed to train rehabilitation professionals in the clinical management of acute spinal cord injury–associated psychological distress, and to measure the impact of this training on the patients’ perceived satisfaction with treatment.
