Nonminimal supersymmetric models that predict a tree-level Higgs mass above the minimal supersymmetric standard model (MSSM) bound are well motivated by naturalness considerations. Indirect constraints on the stop sector parameters of such models are significantly relaxed compared to the MSSM; in particular, both stops can have weak-scale masses. We revisit the stop-catalyzed electroweak baryog...
The results obtained in the CMS experiment at Large Hadron Collider (LHC) by studying electroweak interaction are surveyed.
We study the production and decay of neutral scalars and pseudo-scalars at hadron colliders, in theories where the top-quark mass is the result of a tt̄ condensate. We show that the dominant decay channel for masses below the tt̄ threshold is the flavor changing mode tc. This is a consequence of the non-universal nature of the underlying interactions in all top-condensation models and provides a ...
In this paper we describe a new model of multiple partonic interactions that has been implemented in Herwig++. Tuning its two free parameters we find a good description of CDF underlying event data. We show extrapolations to the LHC.
The muon-proton (μp) collider is an interesting option of the muon collider. Here we discuss the physics potential of the μp collider; especially, leptoquarks and contact interactions. We calculate the sensitivity reach for the second generation leptoquarks and leptogluons, R-parity violating squarks, and μq contact interactions for the μp colliders of various energies and luminosities.
We describe the recent developments to extend the multi-parton interaction model of underlying events in Herwig++ into the soft, nonperturbative, regime. This allows the program to describe also minimum bias collisions in which there is no hard interaction, for the first time. It is publicly available from versions 2.3 onwards and describes the Tevatron underlying event and minimum bias data. T...
We consider the top-quark decay t → τ̃ b and t → τbχ̃1 via explicit Rparity violating interactions in SUSY theories. We discuss the observability of those channels at the Fermilab Tevatron collider. The existing Tevatron data indicate a 95% confidence level upper bound on the coupling to be 0.94 (0.63) for a long-lived (short-lived) χ̃1 with mτ̃ = 70 GeV. At Tevatron Run II with an integrated lumin...

Coherent electron cooling (CEC) has a potential to significantly boost luminosity of high-energy, highintensity hadron-hadron and electron-hadron colliders. In a CEC system, a hadron beam interacts with a cooling electron beam. A perturbation of the electron density caused by ions is amplified and fed back to the ions to reduce the energy spread and the emittance of the ion beam. To demonstrate...
