The fragment cross sections are calculated for reactions of Ne collisions with C , Al , Cu , Sn , Ta , and Pb targets at 600 Mev/nucleon using the the isospin-dependent Boltzmann-Langevin equation. We found that the production cross sections for fragments Z = 2 to 9 are qualitatively reproduced by the present calculations except for C target. In order to understand the effects of heavy ion interaction with biomolecules well, we calculate the fragmentation cross sections for reactions of 12 C + 2 H , 12 C , 14 N , 16 O at beam energies from 50 to 100 MeV/nucleon. It is found that fragment species increase approximately with increasing target mass. The obvious increment of the fragment cross sections for heavier targets at the beam energies from 50 to 80 MeV/nucleon are shown.

Particle Phase Space

Particle inclusive yields from heavy ion reactions are described by a closed form expression which is not limited to a particular type of particle as long as this is produced in individual baryon-baryon encounters with a small probability. This criterion is satisfied for subthreshold pion and kaon production on which we concentrate. Even though the elementary pion and kaon production cross sections can both be described well by three-particle phase space considerations, the final inclusive production rates differ qualitatively from one another. The reasons for this are discussed.

Meson States

This is a review of the production of heavy quark states via relativistic heavy ion collisions in RHIC. The heavy quarks here are c, charm quark, and b, bottom quark. The states are charmonium meson states Ψ ( n S ) , with n = 1,2 and upsilon meson states Υ ( m S ) , with m = 1,2,3. Quantum Chromodynamics (QCD) sum rules were used to derive the result that the Ψ ( 2 S ) and Υ ( 3 S ) are mixed hybrid states, which increase their production cross sections. We also review the Ψ ( n S ) and Υ ( m S ) production cross sections via Cu-Cu and Au-Au collisions, which are very important for this review of the production of heavy quark states in RHIC. The possible detection of the Quark Gluon Plasma (QGP) is also reviewed.

Abstract We describe pair-production models of spin-0 and spin-½ magnetic monopoles and high-electric-charge objects in proton-proton and heavy-ion collisions, considering both the Drell-Yan and the photon-fusion processes. In particular, we extend the Drell-Yan production model of spin-½ high-electric-charge objects to include Z0-boson exchange for proton-proton collisions. Furthermore, we explore spin-½ and, for the first time, spin-0 production in ultraperipheral heavy-ion collisions. With matrix element calculations and equivalent photon fluxes implemented in MadGraph5_aMC@NLO, we present leading-order production cross sections of these mechanisms in √s = 14 TeV proton-proton collisions and √sNN = 5.5 TeV ultraperipheral lead-lead collisions at the LHC. While the mass range accessible in ultraperipheral lead-lead collisions is much lower than that in proton-proton collisions, we find that the theoretical production cross sections are significantly enhanced in the former for masses below 82 GeV.
