Rare and CP-Violating K and B Decays in the Littlest Higgs Model with T-Parity
Monika Blanke, Andrzej J. Buras, Anton Poschenrieder +4
We calculate the most interesting rare and CP-violating K and B decays in the Littlest Higgs model with T-parity. We give a collection of Feynman rules including v^2/f^2 contributi…
Lower Bounds on Delta M_{s,d} from Constrained Minimal Flavour Violation
Monika Blanke, Andrzej J. Buras
We demonstrate that in the class of models with Constrained Minimal Flavour Violation (CMFV), in which the CKM matrix is the only source of CP violation and B^0_q-\bar B^0_q mixing…
Another Look at the Flavour Structure of the Littlest Higgs Model with T-Parity
Monika Blanke, Andrzej J. Buras, Anton Poschenrieder +4
We discuss the mixing matrix V_Hd that describes the charged and neutral current interactions between ordinary down-quarks and up- and down-mirror quarks in the Littlest Higgs Mode…
Another Look at Minimal Lepton Flavour Violation, l_i -> l_j gamma, Leptogenesis, and the Ratio M_nu/ Lambda_LFV
Gustavo C. Branco, Andrzej J. Buras, Sebastian Jager +2
We analyze lepton flavour violation (LFV), as well as generation of the observed baryon-antibaryon asymmetry of the Universe (BAU) within a generalized minimal lepton flavour viola…
Rare K and B Decays in the Littlest Higgs Model without T-Parity
Andrzej J. Buras, Anton Poschenrieder, Selma Uhlig +1
We analyze rare K and B decays in the Littlest Higgs (LH) model without T-parity. We find that the final result for the Z^0-penguin contribution contains a divergence that is gener…
Minimal Flavour Violation Waiting for Precise Measurements of Delta M_s, S_{psi phi}, A^s_SL, |V_ub|, gamma and B^0_{s,d} -> mu+ mu-
Monika Blanke, Andrzej J. Buras, Diego Guadagnoli +1
We emphasize that the recent measurements of the B^0_s - bar B^0_s mass difference Delta M_s by the CDF and D0 collaborations offer an important model independent test of minimal f…
Particle-Antiparticle Mixing, epsilon_K, Delta Gamma_q, A_SL^q, A_CP(B_d -> psi K_S), A_CP(B_s -> psi phi) and B -> X_{s,d} gamma in the Littlest Higgs Model with T-Parity
M. Blanke, A. J. Buras, A. Poschenrieder +3
We calculate a number of observables related to particle-antiparticle mixing in the Littlest Higgs model with T-parity (LHT). The resulting effective Hamiltonian for Delta F=2 tran…
