Testing Cp Violation and Universal Extra Dimensions at Future Colliders
نویسنده
چکیده
A 1 TeV linear ee collider with high luminosity and polarized beams is now a distinct possibility. If spin rotators can produce transversely polarized beams (TPB), providing two more vectors, they would make it possible to observe CP violation by observing a single final-state particle without measuring its spin. Two specific processes have been considered: a) ee → tt̄1,2 The four-Fermi Lagrangian of beyond the SM contact eētt̄ interactions (CI), after Fierz transformation, takes the form

About Mass, CP and Extra Dimensions
We discuss the notion of mass, mostly for fermions, and its relation to the breaking of CP invariance, the natural symmetry of gauge interactions. In a first model, we show how compactification on a Vortex in 2 extra dimensions leads to a replication of generations in 3+1, with challenging mass patterns, and testable consequences in flavour-changing neutral currents (familynumber conserving), b...
متن کاملSusy at the Linear Colliders: Working Group Summary
I summarise the activities of the different members of the SUSY working group. There have been two major areas of activity: 1) precision measurement of the SUSY particle masses/couplings and hence those of the SUSY model parameters, 2) investigations into SUSY searches at ee, γγ, γe and ee colliders, in the nonstandard scenarios such as explicit CP violation, R-parity violation and Anomaly Medi...
متن کاملCp Physics at E + E ? Colliders
The origin and nature of CP violation is one of the most important questions in elementary particle physics, and studies of B meson decay are expected to be the key to understanding this phenomenon. Most B meson decay results come from experiments at e + e ? colliders, and this type of facility will play a major role in elucidating CP violation. I discuss the contributions toward understanding ...
متن کاملCP Violation in B and K Decays : 2003 Andrzej
These lectures give a brief description of CP violation in B and Kmeson decays with particular emphasize put on the determination of the CKM matrix. The following topics will be discussed: i) The CKM matrix, the unitarity triangle and general aspects of the theoretical framework, ii) Particle-antiparticle mixing and various types of CP violation, iii) Standard analysis of the unitarity triangle...
متن کاملCERN-TH.6806/93 CP Violation in t¯t Production at e + e − Colliders
The general production and decay mechanism of tt̄ in future high-energy ee colliders has been investigated in a model-independent way, focusing on an observation of possible CP violation. Angular asymmetries sensitive to CP violation either in the production or in the subsequent decays have been found. General considerations are illustrated through 1-loop effects induced by gluino exchange in th...
