Recent Results in Physics beyond the Standard Model at Hera
نویسنده
چکیده
Recents results in Physics beyond the Standard Model at the e + p collider HERA with the H1 and ZEUS detectors are presented. As no evidence for excited fermions or MSSM supersymmetric particles has been found using an integrated luminosity up to 20 pb ?1 , new limits are derived. The status of events with an isolated high energy lepton and missing transverse momentum is also reported.

Beyond the Standard Model Physics at Hera
Recent results on physics beyond the Standard Model from the HERA ep collider are discussed, based on samples of 37 pb ?1 and 47 pb ?1 of data collected by the H1 and ZEUS Collaborations, respectively, during 1994{1997. Presented are limits on leptoquarks, contact interactions, supersymmetry, and excited fermions. Also discussed are an excess of events with high p T muons and missing transverse...
متن کاملSearch For New Particles at HERA
Recent results on searches for physics beyond the Standard Model obtained by the H1 and ZEUS experiments are reported here. After a brief introduction to the HERA collider, indirect searches for contact interactions and extra-dimensions are presented as well as direct searches for new physics including leptoquarks, leptonflavour violation, squarks produced by R-parity violation and excited ferm...
متن کاملSearch for Rp-violating SUSY and excited fermions at HERA
Recent results from searches for physics beyond the Standard Model (SM) in e-proton collisions at a center of mass energy of 300 – 318 GeV at HERA are presented. Searches for excitations of fermions and for the production of squarks in R-parity-violating Supersymmetry (SUSY) are reviewed.
متن کاملResults on Searches beyond the Standard Model at Hera
Signals of physics beyond the Standard Model at HERA have been searched for by the H1 and ZEUS collaborations. Results are reported about searches of contact interaction effects, leptoquarks, R-parity violating squarks, excited fermions and single top production. The analyses used the data set collected during the HERA phase I, consisting in about 110 (15) pb of ep (e−p) collisions per experime...
