A Test of SU(15) at HERA Using The HELAS Program

Abstract

A possible SU(15) process at HERA is investigated. The process that we consider is $e^- P\ra \barν_e μ^- μ^- +anything$ through the exchange of new heavy gauge bosons $X^{-}$ and $X^{--}$ which are predicted in SU(15). This process produces two easily observable like-sign muons in the final state. The cross section of this process is calculated by using HELAS and VEGAS programs, and PDF-library functions. The cross section turns out to be small to be observed in near future.
