The top quark could provide very important information for the Standard Model extensions due to its large mass close to the electroweak symmetry breaking scale. In this work, anomalous single top ...production is studied by using γp→W+b process at the LHeC based γp collider. The sensitivity to anomalous coupling κ/Λ could be reached down to 0.01 TeV−1.
In composite models with colored preons leptogluons (l8) has a same status with leptoquarks, excited leptons and quarks, etc. We analyze resonant production of color octet electron (e8) at QCD ...Explorer stage of the Large Hadron electron Collider (LHeC). It is shown that the e8 discovery at the LHeC simultaneously will determine the compositeness scale.

Discoveries at the LHC will soon set the physics agenda for future colliders. This report of a CERN Theory Institute includes the summaries of Working Groups that reviewed the physics goals and ...prospects of LHC running with 10 to 300 fb−1 of integrated luminosity, of the proposed sLHC luminosity upgrade, of the ILC, of CLIC, of the LHeC and of a muon collider. The four Working Groups considered possible scenarios for the first 10 fb−1 of data at the LHC in which (i) a state with properties that are compatible with a Higgs boson is discovered, (ii) no such state is discovered either because the Higgs properties are such that it is difficult to detect or because no Higgs boson exists, (iii) a missing-energy signal beyond the Standard Model is discovered as in some supersymmetric models, and (iv) some other exotic signature of new physics is discovered. In the contexts of these scenarios, the Working Groups reviewed the capabilities of the future colliders to study in more detail whatever new physics may be discovered by the LHC. Their reports provide the particle physics community with some tools for reviewing the scientific priorities for future colliders after the LHC produces its first harvest of new physics from multi-TeV collisions.

This chapter of the “Flavor in the era of LHC” workshop report discusses flavor-related issues in the production and decays of heavy states at the LHC at high momentum transfer
Q
, both from the ...experimental and the theoretical perspective. We review top quark physics, and discuss the flavor aspects of several extensions of the standard model, such as supersymmetry, little Higgs models or models with extra dimensions. This includes discovery aspects, as well as the measurement of several properties of these heavy states. We also present publicly available computational tools related to this topic.
