... 30σ) from three-body J/ψ → γωφ phase space is observed near the ωφ mass threshold, which is consis- tent with the previous observation reported by the BE- SII ... See full document

... Dramatic progress has been made in the charmonium spectroscopy above open charm threshold in the BESIII experiment. A new class of charged charmonium-like states has been discovered, which must contain at ... See full document

... caused by a gradual change in the detection efficiency of the PRCs which was modeled by using a fourth order polynomial in time. Since the GRAPES-3 muon telescope consists of sixteen modules, a total of 120 independent ... See full document

... 16 azimuthal towers, each built from 14 longitudinal mod- ules. The 2 front modules form the electromagnetic sec- tion, and the 12 rear modules form the hadronic section. The calorimeter is made of stacks of ... See full document

... There is no a-priori reason following from QCD why only Mesons and Baryons should exist as bound states of quarks. Objects such as di-baryons (6 quark states), tetra quarks (two quark / two anti -quark states), ... See full document

... In the atmospheric sector, the disappearance of muon neutrinos was first established by the Super- Kamiokande experiment [1] and then confirmed with accelerators by K2K [2] and MINOS [3] long- baseline experiments. ... See full document

... ATLAS has also studied production of prompt photons produced in Pb+Pb collisions [17]. Prompt photons have two primary sources: direct emission via quark-gluon Compton scattering or quark- antiquark annihilation, or in ... See full document

... These results may look surprising because it seems unlikely that objects of a few MeV binding energy per nucleon are participating in multiple thermalization collisions which generate the common velocity field ... See full document

... In the analysis two Monte Carlo (MC) samples are used, which simulate respectively the signal B ± → J /ψ K ± → μ + μ − K ± and the backgrounds from b b ¯ production, with b b ¯ → J /ψ X → μ + μ − X, which are ... See full document

... Abstract. A study of processes with double parton interactions (DPI) in p p ¯ collisions collected by DØ detector at the Tevatron collider at √ s = 1.96 TeV is presented. The study includes measurements of DPI event ... See full document
