Status of SIMBA
Florian U. Bernlochner, Heiko Lacker, Zoltan Ligeti +3
The goal of the SIMBA collaboration is to provide a global fit to the available data in inclusive B -> X_s gamma and B -> X_u l nu decays. By performing a global fit one is able to…
Supermodels: Early new physics at the LHC?
Zoltan Ligeti
We investigate new physics that could be discovered with very little LHC data, beyond the expected sensitivity of the Tevatron. We construct "supermodels", for which the LHC sensit…
Towards a global fit to extract the B->Xs gamma decay rate and Vub
Florian U. Bernlochner, Heiko Lacker, Zoltan Ligeti +3
The total B->Xs gamma decay rate and the CKM-matrix element Vub play an important role in finding indirect evidence for new physics affecting the flavor sector of the Standard Mode…
Treating the b quark distribution function with reliable uncertainties
Zoltan Ligeti, Iain W. Stewart, Frank J. Tackmann
The parton distribution function for a b quark in the B meson (called the shape function) plays an important role in the analysis of the B -> X_s gamma and B -> X_u l nu data, and…
Precise predictions for B -> Xs l+ l- in the large q^2 region
Zoltan Ligeti, Frank J. Tackmann
The inclusive B -> Xs l+ l- decay rate in the large q^2 region (q^2 > m_{ψ'}^2) receives significant nonperturbative corrections. The resulting uncertainties can be drastically red…
Deciphering top flavor violation at the LHC with B factories
Patrick J. Fox, Zoltan Ligeti, Michele Papucci +2
The LHC will have unprecedented sensitivity to flavor-changing neutral current (FCNC) top quark decays, whose observation would be a clear sign of physics beyond the standard model…
