SEARCH FOR EXCITED FERMIONS AT HERA H1 Collaboration

ثبت نشده
چکیده

We present a search for excited fermions in e+p scattering at HERA using H1 data with an integrated luminosity of 37 pb 1. All electroweak decays of excited leptons, ` ! ` ; `W; `Z0 are considered. The excited quarks are searched for in the q ! q and qW channels. The analysis considers Z0 and W hadronic decays and first generation leptonic decays. No evidence for new particle production is found. Mass dependent exclusion limits on cross sections and coupling constants are derived.

Search for Excited Fermions in Ep Collisions at Hera *

Heavy excited electrons and neutrinos have been sought by the H1 and ZEUS experiments at HERA. For the e * (ν *) searches, 120 pb −1 (16 pb −1) of ep collision data have been analysed. No evidence for any excited lep-ton has been found, and limits on the characteristic couplings have been derived.

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...

Searches at Hera

Searches for physics beyond the Standard Model have been performed in high-energy e ± p collisions at HERA. No significant deviation from the Standard Model has been observed while searching for contact interactions, extra dimensions, lep-toquarks, R-parity violating squarks and excited fermions. Exclusion limits have been inferred which extend or complement bounds from other colliders. The H1 ...

Search 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...

Resonance Searches at HERA

Inclusive production of K SK 0 S in ep collisions was studied with the ZEUS detector. Significant production of J = 2 tensor mesons and of the 0 glueball candidate f0(1710) was seen. Masses and widths were compared with previous experiments. The H1 Collaboration saw a charm pentaquark candidate in the D∗p spectrum at 3.1 GeV, which was not confirmed by a ZEUS higher statistics search. With the ...
