Searches and Electroweak Measurements at Hera
نویسنده
چکیده
(on behalf of the H1 and ZEUS collaborations) The H1 and ZEUS collaborations have used the HERA I data to search for physics beyond the SM and to test electroweak physics in electron-proton collisions. The new period of data taking (HERA II) has started and first HERA II analyses become available. An overview is given of recent highlights, including isolated lepton and multi-lepton events, tests of models of new physics and the first systematic search for deviations in all final states with high transverse momentum.

High Q2 Cross Sections, Electroweak Measurements and Physics beyond Standard Model at Hera
HERA, the only ep collider, operated in the years 1992-2007 at centre-of-mass energies of 300320 GeV in Hamburg, Germany. Deep inelastic neutral (ep → eX) and charged (ep → νX) current scattering at HERA provides the possibility to study the structure of the proton, the dynamics of strong interactions and test quantum chromodynamics (QCD) over a huge kinematic range. Both, neutral and charged c...
متن کاملPursuing the Strange Stop Interpretation of the HERA Large - Q 2 Data
We explore the possible interpretation of the large-Q 2 anomaly reported by the H1 and ZEUS collaborations in terms of stop squark production off a strange quark in the proton via an R-violating interaction. This " strange stop " interpretation is constrained by LEP measurements of the Z → e + e − decay rate in addition to constraints from the electroweak ρ parameter and CDF and D0 searches for...
متن کاملElectroweak Physics at HERA
Results on the measurement of electroweak processes in e±p collisions at HERA by the H1 and ZEUS experiments are presented. All data collected at HERA corresponding to a total integrated luminosity of about 1 fb−1 are used for most of the measurements. Inclusive cross section measurements of deep inelastic neutral current (ep → eX) and charged current (ep → νX) scattering are shown. The influen...
متن کاملElectroweak Physics at Hera: Introduction and Summary 1
A high luminosity upgrade of HERA will allow the measurement of standard model parameters and the neutral current couplings of quarks. These results will have to be consistent with other precision measurements or indicate traces of new physics. The analysis of W production will complement future results of LEP 2 and the Tevatron. We summarize the main results and conclusions obtained by the wor...
