Pions and kaons at 1-2 A GeV: Effect of in-medium NN → N∆ cross section
Pion multiplicity in heavy-ion collisions at the beam energies of about 1 A GeV [1, 2] is usually overpredicted by transport calculations with vacuum cross sections. Recently [3] we proposed to take into account the in-medium modifications of the NN → N∆ cross section, namely, the exchange pion collectivity, vertex renormalization by the contact nuclear interactions and Dirac effective masses o...
متن کاملThe Ratio of the Direct Photon Production Cross Section at 630 GeV and at 1800 GeV
We measure the ratio of the isolated direct photon prodution cross section at √ s = 630 GeV to that at √ s = 1800 GeV for the central (|η| < 0.9) and forward (1.6 < |η| < 2.5) rapidity regions. We compare the result with next to leading order QCD predictions using CTEQ parton distribution functions.
متن کاملCross section of the reaction
Using 3.07 pb of data collected in the energy range 0.60–0.97 GeV by CMD-2, about 150 events of the process ee → ππππ have been selected. The energy dependence of the cross section agrees with the assumption of the a1(1260)π intermediate state which is dominant above 1 GeV. For the first time ππππ events are observed at the ρ meson energy. Under the assumption that all these events come from th...
متن کاملM ay 2 01 0 Υ cross section in p + p collisions at √ s = 200 GeV
We report on a measurement of the Υ(1S+2S+3S) → e + e − cross section at midrapidity in p + p collisions at √ s = 200 GeV. We find the cross section to be 114 ± 38 (stat. + fit) +23 −24 (syst.) pb. Perturbative QCD calculations at next-to-leading order in the Color Evaporation Model are in agreement with our measurement, while calculations in the Color Singlet Model underestimate it by 2σ. Our ...
متن کاملScalar mesons above and below 1 GeV
We show that two nonets and a glueball provide a consistent description of data on scalar mesons below 1.7 GeV. Above 1 GeV the states form a conventional qq̄ nonet mixed with the glueball of lattice QCD. Below 1 GeV the states also form a nonet, as implied by the attractive forces of QCD, but of more complicated nature. Near the center they are (qq)3̄(q̄q̄)3 in S-wave, with some qq̄ in P-wave, but ...
