Muon Collider Physics at Very High Energies
Muon colliders might greatly extend the energy frontier of collider physics. One can contemplate circular colliders with center-of-mass energies in excess of 10 TeV. Some physics issues that might be relevant at such a machine are discussed.
متن کاملIn Search of New Physics at Hera
An update is presented of the analysis of the H1 experiment at the HERA electron/positron-proton collider including the luminosity taken in 1997. Topics covered are: Status of the excess in deep-inelastic positron-proton scattering at very high Q 2 reported earlier and new results on neutral and charged current cross-sections at high Q 2 , limits on the couplings of lep-toquarks of the 1st and ...
متن کاملHigh Q Physics at HERA and Searches for New Particles
Preliminary results from H1 and ZEUS on Deep Inelastic Scattering (DIS) at high momentum transfer squared Q are presented. Used are all available ep data accumulated by the H1 and ZEUS experiments between 1994 and 1997, corresponding to integrated luminosities of 37pb and 47pb, respectively. The anomalies observed at high Q in the 1994 to 1996 data still remain, though with less significance. S...
متن کاملSearches for New Physics at Hera
The H1 and ZEUS collaborations have searched for signals of physics beyond the Standard Model in e ± p collisions at a center-of-mass energy of 301−319 GeV. During the HERA I phase each experiment accumulated an integrated luminosity of about 110 pb −1 for e + p and about 15 pb −1 for e − p collisions. The data have been analysed searching for contact interaction effects, leptoquarks, lepton fl...
متن کاملSearches for New Physics at Hera
The latest results from the H1 and ZEUS collaborations are presented on rare Standard Model processes and searches for physics Beyond the Standard Model. Intriguing events containing high transverse momentum leptons are observed by H1 and many competitive limits are set by both collaborations on the production of new particles in a variety of supersymmetry scenarios.
