The results of the SERP-E-184 experiment at the U-70 accelerator (IHEP, Protvino) are presented. Interactions of the 70 GeV proton beam with C, Si and Pb targets were studied to detect decays of charmed $D^0$, $overline D^0$, $D^+$, $D^-$ mesons and $Lambda _c^+$ baryon near their production threshold. Measurements of lifetimes and masses are shown a good agreement with PDG data. The inclusive cross sections of charm production and their A-dependencies were obtained. The yields of these particles are compared with the theoretical predictions and the data of other experiments. The measured cross section of the total open charm production ($sigma _{mathrm {tot}}(coverline c)$ = 7.1 $pm $ 2.3(stat) $pm $1.4(syst) $mu $b/nucleon) at the collision c.m. energy $sqrt {s}$ = 11.8 GeV is well above the QCD model predictions. The contributions of different species of charmed particles to the total cross section of the open charm production in proton-nucleus interactions vary with energy.

The results of analysis SERP-E-184 experiment data, obtained with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates are presented. For 3-prongs charged charmed mesons decays, event selection criteria were developed
The results of data handling for E-184 experiment obtained with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates are presented. Two-prongs neutral charmed D0 and v{D}0 -mesons decays were selected. Signal / backgro
We report on the SVD-2 experiment data analysis aimed to search for an exotic baryon state, the $Theta^+$-baryon, in a $pK^0_s$ decay mode with IHEP U-70 accelerator proton beam at $70 GeV/c$. A resonant structure with $M=1526pm3(stat.)pm 3(syst.)~Me
We report first results on a deep sub-threshold production of the doubly strange hyperon $Xi^-$ in a heavy-ion reaction. At a beam energy of 1.76A GeV the reaction Ar+KCl was studied with the High Acceptance Di-Electron Spectrometer (HADES) at SIS18/
