We present a search for the e+e− decay of hypothetical dark photon, also named U vector boson, in inclusive dielectron spectra measured by HADES p(3.5 GeV) + p, Nb reactions, as well Ar (1.756 GeV/u) KCl reaction. An upper limit on kinetic mixing parameter squared ϵ2 at 90% CL has been obtained mass range MU=0.02–0.55 GeV/c2 and is compared with world data set. For masses 0.03–0.1 GeV/c2, lowered respect to previous results, allowing now exclude large part region favored muon g−2 anomaly....
The angular distributions of the cross section, proton analyzing power, and all polarization transfer coefficients $\stackrel{\ensuremath{\rightarrow}}{p}d$ elastic scattering were measured at 250 MeV. range center-of-mass angles was $10\ifmmode^\circ\else\textdegree\fi{}--165\ifmmode^\circ\else\textdegree\fi{}$ for section about $10\ifmmode^\circ\else\textdegree\fi{}--95\ifmmode^\circ\else\textdegree\fi{}$ coefficients. These are first measurements a complete set observables intermediate...
We present data on dielectron emission in proton induced reactions a Nb target at 3.5 GeV kinetic beam energy measured with HADES installed GSI. The represent the first high statistics measurement of proton-induced radiation from cold nuclear matter kinematic regime, where strong medium effects are expected. Combined good mass resolution 2%, it is sensitive to changes spectral functions vector mesons, as predicted by models for hadrons rest or small relative momenta. Comparing e+e invariant...
A feasibility study has been performed in order to investigate the performance of HADES detector measure electromagnetic decays hyperon resonances $\Sigma(1385)^0$, $\Lambda(1405)$ and $\Lambda{\Lambda}(1520)$ as well production double strange baryon systems $\Xi^-$ $\Lambda\Lambda$ p+p reactions at a beam kinetic energy 4.5 GeV. The existing will be upgraded by new Forward Detector, which extends acceptance into range polar angles that plays crucial role for these investigations. analysis...
Measurements of the angular dependence vector analyzing powers Ay and differential cross-section in dp -elastic scattering at $ T_d = 2$ GeV for range from 10^{\circ}$ to 35^{\circ}$ c.m.s. have been performed. The obtained data are good agreement with existing theoretical calculations made framework relativistic multiple model.
Recent results on the deuteron analyzing powers obtained in collisions of polarized deuterons with protons and light nuclei at intermediate high energies are reported. The sensitive to spin structure short range correlations. prospects program for hadronic reactions Nuclotron-NICA facility is discussed. polarimetry developments also presented.
