标题： Searches for Leptoquarks, Squarks in $\not R_p$ SUSY and Excited Fermions at HERA

摘要： HERA实验H1和ZEUS对寻找轻子夸克、违反$R_p$对称性的标量夸克超对称模型中的标量夸克以及激发费米子的实验结果进行了回顾。自1994年以来，在电子-质子和正电子-质子对撞中，未观测到新粒子产生的证据。这些新粒子的质量和耦合强度的严格限制在适当的情况下与LEP、Tevatron和低能实验的结果进行了比较。 显示英文摘要

摘要： Various searches for leptoquarks, scalar quarks in $R_p$-violating supersymmetric models, and excited fermions performed by the HERA experiments H1 and ZEUS are reviewed. No evidence for new particle production was observed from data collected by both experiments since 1994 in either electron-proton and positron-proton collisions. Stringent limits derived on the masses and couplings of these new particles are compared whenever appropriate with those from LEP, the Tevatron and low energy experiments.
