Constraint on rho-bar, eta-bar from B to K*pi
Michael Gronau, Dan Pirjol, Amarjit Soni +1
A linear CKM relation, , involving a range for , , is obtained from amplitudes m…
On the flavor structure of the littlest Higgs model
Svjetlana Fajfer, Jernej F. Kamenik
We investigate the Yukawa sector for up-like quarks in the Lee's version of the Littlest Higgs model. We derive general quark mass and mixing formulae and study leading order contr…
Probing electroweak physics using B -> XM decays in the endpoint region
Junegone Chay, Chul Kim, Adam K. Leibovich +1
Using soft-collinear effective theory we describe at leading order in 1/m_b all the semi-inclusive hadronic B -> XM decays near the endpoint, where an energetic light meson M recoi…
Updated constraints on new physics in rare charm decays
Svjetlana Fajfer, Nejc Kosnik, Sasa Prelovsek
Motivated by recent experimental results on charm physics we investigate implications of the updated constraints of new physics in rare charm meson decays. We first reconsider effe…
Probing Minimal Flavor Violation at the LHC
Yuval Grossman, Yosef Nir, Jesse Thaler +2
If the LHC experiments discover new particles that couple to the Standard Model fermions, then measurements by ATLAS and CMS can contribute to our understanding of the flavor puzzl…
Chiral loop corrections to weak decays of B mesons to positive and negative parity charmed mesons
Jan O. Eeg, Svjetlana Fajfer, Jernej Kamenik
We determine chiral loop corrections to the B meson decay amplitudes to positive and negative parity charmed mesons within a framework which combines heavy quark and chiral symmetr…
Grand Unification with and without Supersymmetry
Alejandra Melfo
Grand Unified Theories based on the group SO(10) generically provide interesting and testable relations between the charged fermions and neutrino sector masses and mixings. In the…
Probing seesaw at LHC
Borut Bajc, Miha Nemevsek, Goran Senjanovic
We have recently proposed a simple SU(5) theory with an adjoint fermionic multiplet on top of the usual minimal spectrum. This leads to the hybrid scenario of both type I and type…
Enhanced effects on extracting γfrom untagged B^0 and B_s decays
Michael Gronau, Yuval Grossman, Ze'ev Surujon +1
The weak phase γcan be determined using untagged B^0\to DK_S or B_s\to Dϕ, Dη^{(')} decays. In the past, the small lifetime difference y\equiv ΔΓ/(2Γ) has been neglected in B^0, wh…
Penguin pollution estimates relevant for phi_2/alpha extraction
Jure Zupan
A review of methods to extract the standard CKM unitarity triangle angle alpha is provided. The sizes of related theoretical errors are reviewed.
