Enhancing Squark/Leptoquark Production by Increasing the HERA Beam Energies
Abstract
The cross section for production of R-parity violating squarks () or leptoquarks () with masses above 200 GeV by positron-proton scattering at HERA can be substantially increased by a moderate increase of the beam energies. If, for example, the positron energy is raised from 27.5 to 32.5 GeV and the proton energy from 820 to 1000 GeV, the production cross section for masses of 200 - 230 GeV increases by a factor of about 2-6 and the search range for is extended by about 40 GeV to masses of 270 - 280 GeV. In this report event yields are presented for beam energies in the range and . Also presented is the rate of background events expected from Standard Model neutral and charged current scattering.
