Leptoquark Pair Production at HERA

The scalar and vector leptoquark pair production cross sections for deep inelastic ep scattering are calculated. Estimates are presented for the search potential at HERA.

Leptoquark/Squark Interpretation of HERA Events: Virtual Effects in e+e− Annihilation to Hadrons

In reference to the recently observed high Q, large x events in deep-inelastic positron–proton scattering at HERA, various leptoquark and supersymmetric scenarios are discussed. We study the impact of virtual leptoquark or R-parity breaking squark exchange as well as generic contact interaction on the production of quark–antiquark pairs in ee annihilation, in particular at LEP2. ∗ Supported by ...

On Virtual Characters that Can See

A virtual character (VC) acts within its virtual world boundaries, but with vision sensory capabilities, it may be expected to explore the real world and interact with the intelligent beings there. Such a VC can be equipped with algorithms to localize humans, recognize and communicate with them. These perceptual capabilities prompt a sophisticated cognitive architecture (CA), enabling our VC to...

Enhancing Squark/Leptoquark Production by Increasing the HERA Beam Energies

The cross section for production of R-parity violating squarks (q̃) or leptoquarks (LQ) 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 q̃/LQ production cross section for masses of 200 – 230...
