We consider several hints for new physics involving CP-asymmetries in B-decays and interpret them in terms of generic contributions to effective Wilson coefficients. The effects we focus on are: the differences in the fitted value of sin 2β versus the ones directly measured via the time dependent CP asymmetries in B → J/ψK or via B → (φ, η ′)K; the(More)
We study logarithmically enhanced electromagnetic corrections to the decay rate in the high dilepton invariant mass region as well as corrections to the forward backward asymmetry (FBA) of the inclusive rare decay ¯ B → X s ℓ + ℓ −. As expected, the relative effect of these corrections in the high dilepton mass region is around −8% for the muonic final(More)
The direct CP asymmetry in the untagged inclusive channel ¯ B → X s+d γ provides a strict test of the standard model. It has been shown beyond the partonic level that this asymmetry is negligibly small thanks to U-spin relations and to the unitarity of the CKM matrix. In the present paper we investigate this relation beyond the SM; in particular, we analyse(More)
We report recent results in rare B decays. Our focus will be on b → dγ and b → sℓ + ℓ − transitions. We discuss their impact on the CKM phenomenology and their role within our search for new physics. In particular, we analyse the impact of a recent lattice QCD estimate of the B → K * form factor at zero recoil. We also briefly discuss the presently(More)
This white paper was assembled by Scott Dodelson with input from many of the cosigners. It is part of the efforts of NASA'a Primordial Polarization Program Definition Team (PPPDT), Shaul Hanany chair, and of a NASA award to Steve Meyer and colleagues entitled " A study for a CMB Probe of Inflation " (07-ASMCS07-0012).
Information on species thermal physiology is extremely important to understand species responses to environmental heterogeneity and changes. Thermography is an emerging technology that allows high resolution and accurate measurement of body temperature, but until now it has not been used to study thermal physiology of amphibians in the wild. Hydromantes(More)
Relationships between species and their habitats are not always constant. Different processes may determine changes in species-habitat association: individuals may prefer different habitat typologies in different periods, or they may be forced to occupy a different habitat in order to follow the changing environment. The aim of our study was to assess(More)
Measurements of the time-dependent CP asymmetry in the decay B 0 d (t) → π + π − and its charge conjugate by the BELLE and BABAR collaborations currently yield C +− ππ = −0.46 ± 0.13 and S +− ππ = −0.74 ± 0.16, characterizing the direct and mixing-induced CP asymmetries, respectively. We study the implication of these measurements on the CKM phenomenology(More)
The B-factories results provide an impressive confirmation of the Standard Model (SM) description of flavor and CP violation. Nevertheless, as more data were accumulated, deviations in the 2.5-3.5 σ range have emerged pointing to the exciting possibility of new CP-odd phase(s) and flavor violating parameters in B-decays. Primarily this seems to be the case(More)
