Probing Contact Interactions at High Energy Lepton Colliders *
نویسنده
چکیده
Fermion compositeness and other new physics can be signalled by the presence of a strong four-fermion contact interaction. Here we present a study of leqq and !&?e’ contact interactions using the reactions: et!? --f e’+e’-, b&, CC at future e+elinear colliders with fi = 0.5 5 TeV and p+pcolliders with 4 = 0.5,4 TeV. We find that very large compositeness scales can be probed at these machines and that the use of polarized beams can unravel their underlying

Search for Particles and Forces Beyond the Standard Model at HERA ep and Tevatron pp̄ Colliders ∗
A review of searches for physics beyond the Standard Model carried out at high energy leptonhadron and hadron-hadron facilities is presented, with emphasis on topics of interest for future data taking at the upgraded Tevatron pp̄ and HERA ep colliders. The status and discovery prospects are discussed for leptoquarks, Technicolour and supersymmetry, forbidden lepton and quark flavourchanging proc...
متن کاملProduction of Excited Neutrino at LHC
The proliferation of quarks and leptons can be naturally explained by the assumption that they are composite objects. According to models of compositeness[1], known fermions are bound states of more fundamental constituents – preons [2] or a fermion and a boson [3]. In the framework of these models, constituents of known fermions interact by means of new strong gauge interactions. One of the ma...
متن کاملγγ Physics at Linear Colliders
A high-energy lepton-lepton collider will give us a unique possibility to study eγ and γγ interactions at high energies. The high-energy photons can be generated by Compton back-scattering of laser light on the high-energy lepton beams. With slightly reduced luminosities for eγ and γγ collisions compared to the lepton-lepton collider one, unique and complementary studies can be performed. A lin...
متن کاملSearches 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 ...
متن کاملPhoton-Induced Physics with Heavy-Ion Beams in ALICE
Photon-induced interactions have traditionally been studied with lepton beams in fixed target experiments and at colliders. But two–photon and photon–hadron interactions can occur also when the lepton beams are replaced by high energy protons or heavy ions[1,2]. The electromagnetic interactions can be studied in ultra-peripheral collisions where the impact parameters are larger than the sum of ...
