متن کاملExact Dirac equation calculation of ionization and pair production induced by ultrarelativistic heavy ions
An exact solution of the time-dependent Dirac equation for ionization and pair production induced by ultrarelativistic heavy ion collisions is presented. Exact transition probabilities, equivalent to those that would be obtained in an untruncated basis coupled channels calculation, are presented. Exact bound-electron positron pair production probabilities are calculated to be mostly smaller tha...
متن کاملLeading Order Pqcd Hadron Production and Nuclear Modification Factors at Rhic and the Lhc
Abstract Hadron production in leading order pQCD is reviewed. The shape of the single inclusive particle spectra is well described for pT ≥ 2 − 3 GeV at center of mass energies from 20 GeV to 2 TeV. The phenomenological K-factor is found to decrease systematically with √ s. For ultra-relativistic heavy ion reactions the calculation is augmented with the effects of initial multiple parton scatte...
متن کاملMeasurement of Electromagnetic Cross Sections in Heavy Ion Interactions and Its Consequences for Luminosity Lifetimes in Ion Colliders
One of the principal limitations to the luminosity lifetime in high energy heavy ion colliders is the loss of beam particles due to the large cross section for beambeam interactions. At very high energies there are essentially three processes that contribute to the losses: Electron capture, electromagnetic dissociation and hadronic processes. The electron capture proceeds through several differ...
متن کاملSome exact analytical results and a semi-empirical formula for single electron ionization induced by ultrarelativistic heavy ions
The delta function gauge of the electromagnetic potential allows semiclassical formulas to be obtained for the probability of exciting a single electron out of the ground state in an ultrarelativistic heavy ion reaction. Exact formulas have been obtained in the limits of zero impact parameter and large, perturbative, impact parameter. The perturbative impact parameter result can be exploited to...
