Transverse momentum spectra of fermions and bosons produced in strong abelian fields
Abstract
We study the transverse momentum spectra of fermions and bosons produced in strong, time-dependent abelian field. The transverse size of the abelian field is finite, similarly to color strings and ropes. Different time-dependent field strengths are investigated in a kinetic model, and transverse momentum spectra are calculated for fermions and bosons. These spectra display exponential or polynomial behavior at high pT, depending on the given time dependence. We compare our spectra to lattice result for a classical gluon field and obtain surprisingly good agreement in certain cases.
