Charmed particles production in pA-interactions at 70 GeV
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 carbon,
silicon and lead targets were studied to detect decays of charmed , , , mesons and baryon near their production
threshold. Measurements of lifetimes and masses have shown a good agreement
with PDG data. The inclusive cross sections of charm production and their
A-dependencies have been 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 b/nucleon at the collision c.m. energy
= 11.8 GeV is well above the QCD model predictions. The contributions
of different kinds of charmed particles to the total cross section of the open
charm production in proton-nucleus interactions vary with energy.Comment: Presented at 19th International Seminar on High Energy Physics

Preface: “Quarks-2016”, 19th International Seminar on High Energy Physics
The highlights of the most recent CMS results with 13 TeV data will be presented in this overview. The Standard Model precision measurements, including the top quark production, will be shown first. This will be followed by the presentation of Higgs boson studies with the early 13 TeV data. Then the focus will shift to searches for physics beyond the Standard Model, including the searches for several Supersymmetric scenarios, using different analysis techniques. The talk will conclude with searches for the exotic resonances, with an emphasis on studies of the high-mass diphoton production
Localized quench in 1+1 conformal field theory
We study the boundary dual of AdS3 spacetime with a point particle. Particles in AdS3 generate topological defects, which allows to formulate the geodesic image method for boundary correlators. We propose the generalization of the geodesic recipe to arbitrary time intervals in case of the bulk spacetime deformed by a point particle
