Search for TeV scale physics in heavy flavor decays

Abstract

Abstract. The subject of heavy flavour decays as probes for physics at and beyond the TeV scale is covered from the experimental perspective. Emphasis is placed on the more traditional Beyond the Standard Model topics that have potential for impact in the early LHC era, and in anticipation of the B factory upgrade(s). The aim is to explain the physics, without getting too involved in the details, whether experimental or theoretical, to give the interested nonexpert a perspective on the Flavour/TeV link. We cover the forefront topics of CP violation in b → s transitions involving penguin and box diagrams, and probes of charged Higgs, right-handed and scalar interactions. We touch briefly on Υ decay, D 0 mixing, rare K decays, and lepton flavor violating probes in τ decay. Our own phemonenology work is often used for illustration. PACS.

Flavour Theory: 2009

“…Recently new interest arose in models with a sequential 4th generation which is clearly a possibility. In particular George Hou [105][106][107] and subsequently Lenz [108], Soni [109] and their collaborators made extensive analyses of FCNC processes in this framework. See also [110].…”

“…When discussing the (2,1) models, it is important to distinguish between models in which new physics couples dominantly to the third generation of quarks, basically the top quark, and models where there is a new sector of fermions that can communicate with the SM fermions with the help of new gauge interactions. Phenomenological approaches with enhanced Z-penguins [117][118][119], some special Z ′ -models [120][121][122] and the fourth generation models [105,[108][109][110] belong to the first subclass of (2,1), while the LHT model represents the second subclass.…”
