In this document we address an error discovered in the ensemble generation for our calculation of the $I=0$ $K\to\pi\pi$ amplitude (Phys. Rev. Lett. 115, 212001 (2015), arXiv:1505.07863) whereby the same random numbers were used for the two independent quark flavors, resulting in small but measurable correlations between gauge observables separated by 12 units in the y-direction. We conclude that the effects of this error are negligible compared to the overall errors on our calculation.

K ! and " 0 =" in simplied new physics models

The decays K + ! + and KL! 0 , being the theoretically cleanest rare decays of mesons, are very sensitive probes of New Physics (NP). In view of the excellent prospects of reaching the Standard Model…

Quark flavour observables in the Littlest Higgs model with T-parity after LHC Run 1

A new analysis of quark flavour observables in the LHT model in view of the oncoming flavour precision era is presented, taking into account new lower bounds on the symmetry breaking scale and the mirror quark masses from the LHC.

Nonperturbative renormalization of the Delta-S=1 weak Hamiltonian including the G_1 operator

Under renormalization, physical operators can mix with operators which vanish by the equations of motion. Such operators cannot contribute to matrix elements between physical states, but they…

The Role of Flavor in 2016

This talk explores the role of flavor physics to constrain beyond standard model phenomena and future prospects, from a theoretical point of view. Possible implications of some experimental results…

Kaon Theory News

During the last fifteen years B_{s,d} decays, B_{s,d}^0-\bar B^0_{s,d} mixings, CP-violating asymmetries S_{\psi K_S} and S_{\psi\phi} provided the dominant information about the pattern of flavour…
