“…Our results are in very good agreement with the fit labelled "No direct CPV in DCS decays" by HFAG [6], now that HFAG uses the theoretical relation in eq. (1.4) as we suggested in our first paper [1].…”

“…Since 2012, the UTfit Collaboration has performed its own combination of the D mixing experimental data, yielding a quite precise determination of the mixing parameters showing no sign of CP violation [1,2]. The spectacular experimental progress that we have witnessed in the past few years is leading us in the precision charm physics era, calling for substantial theoretical advances to fully exploit the wealth of available data.…”

Sfermion flavor and proton decay in high-scale supersymmetry

The discovery of the Higgs boson with a mass of around 125 GeV gives a strong motivation for further study of a high-scale supersymmetry (SUSY) breaking model. In this framework, the minimal SUSY SU(5) grand unification model may be viable since heavy sfermions suppress the proton decay via color-triplet Higgs exchanges. At the same time, sizable flavor violation in sfermion masses is still allowed by low-energy precision experiments when the mass scale is as high as O(100) TeV, which naturally explains the 125 GeV Higgs mass. In the presence of the sfermion flavor violation, however, the rates and branching fractions of proton decay can be drastically changed. In this paper, we study the effects of sfermion flavor structure on proton decay and discuss the experimental constraints on sfermion flavor violation. We find that proton-decay experiments may give us a valuable knowledge on sfermion flavor violation, and by combining it with the results from other low-energy precision experiments, we can extract insights to the structure of sfermion sector as well as the underlying grand unification model.

“…Using the ETM N f = 2 configurations at four lattice spacings (0.05, 0.07, 0.09, and 0.10 fm), O(a) improved Ostwerwalder-Seiler valence quarks, and pions as light as 280 MeV, they calculate the bag parameters to 3 − 5% precision. This is about five time more precise than current equivalent experimental precision [57,58] and on par with 2020 expectations [59]. FNAL/MILC [60] presented preliminary results for the mixing matrix elements from a calculation using the MILC N f = 2 + 1 asqtad configurations at four lattice spacings (0.045, 0.06, 0.09, and 0.12 fm), asqtad light and FNAL charm valence quarks, and with pions as light as 177 MeV.…”
