K. Cheung et al., IMPACT ON SUPERSYMMETRY-BREAKING MODELS OF THE R-PARITY VIOLATING SQUARK INTERPRETATION OF THE DESY HERA ANOMALY - ART. NO. 057705, Physical review. D. Particles and fields, 5805(5), 1998, pp. 7705
The explanation of a 200 GeV R-parity violating squark to the DESY HER
A high-Q(2) anomaly would have an important impact on supersymmetry-br
eaking models. Here we show that a squark of mass around 200 GeV is di
sallowed in the minimal gauge-mediated SUSY-breaking models in the par
ameter space constrained by the radiative electroweak-symmetry breakin
g and the experimental lower limits on supersymmetric particles, even
after including the large R-parity violating couplings. Supergravity-m
otivated models can, on the other hand, give rise to these scalar quar
ks in a wide range of parameter space. [S0556-2821(98)05217-5].
