Bound-free pair production cross section in heavy-ion colliders from the equivalent photon approach
نویسنده
چکیده
Abstract. Exact calculations of the electron-positron pair production by a single photon in the Coulomb field of a nucleus with simultaneous capture of the electron into the K-shell are discussed for different nuclear charges. Using the equivalent photon method of Weizsäcker and Williams, a simple expression for the bound-free production of ee pairs by colliding very-high-energy fully stripped heavy ions is derived for nuclei of arbitrary charge.

Nuclear form factor , validity of the equivalent photon approximation and Coulomb corrections to muon pair production in photon - nucleus and nucleus - nucleus collisions
We study in detail the influence of the nuclear form factor both on the Born cross section and on the Coulomb corrections to the photo-production of muon pairs off heavy nuclei (γZ → µ + µ − Z) and in heavy-ion collisions (ZZ → ZZµ + µ −). Our findings indicate a number of issues which have not been sufficiently described as yet in the literature: (i) the use of a realistic form factor, based o...
متن کاملBremsstrahlung from Electrons and Positrons in Peripheral Relativistic Heavy Ion Collisions
We study the spectrum of the bremsstrahlung photons coming from the electrons and positrons, which are produced in the strong electromagnetic fields present in peripheral relativistic heavy ion collisions. We compare different approaches, making use of the exact pair production cross section in heavy ion collisions as well as the double equivalent photon approximation. 25.75.-q,13.40.-f Typeset...
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 کاملS ep 1 99 8 Comment on the absence of Coulomb effects on e + e − pair production in ultrarelativistic heavy - ion collisions
In recent works [4]-[6] it was claimed that the Coulomb correction to the ee production cross section in relativistic heavy-ion collisions is absent. We point out that this statement is in obvious contradiction to some well known results. We obtain large Coulomb corrections in the pair production cross section for the RHIC and LHC heavy-ion colliders. Two new large colliders with relativistic h...
متن کاملExtra Dimensions and Higgs Pair Production at Photon Colliders
We show that new physics effects due to extra dimensions can dramatically affect Higgs pair production at photon colliders. We find that the cross section due to extra dimensions with the scale MS of new physics around 1.5 TeV, the cross section can be as large as 0.11 pb (1.5pb) for monochromatic photon collision, γγ → HH, with the collider energy √ s = 0.5(1) TeV for Higgs mass of 100 (350) G...
