The confinement mechanism proposed earlier by the author is applied to estimate the possible parameters of the confining SU(3)-gluonic field in an η-meson. For this aim the electric form factor of an η-meson is nonperturbatively computed in an explicit analytic form. The estimates obtained are also consistent with the width of the electromagnetic decay η → 2γ. The corresponding estimates of the...

The two–loopO(αsGFmt ) corrections to the bb̄ decay rate of the Standard Model Higgs boson as well as its production via ee → ZH will be presented. These QCD corrections are obtained by using a low-energy theorem for light Higgs bosons compared to the top quark mass. The results yield strong screening effects of the O(GFmt ) contributions. After that the two-loop QCD corrections to the γγ and gl...

The precision of the CP phases 2β and 2β(s) determined from the mixing-induced CP asymmetries in B(d)→J/ψK(S) and B(s)→J/ψϕ, respectively, is limited by the unknown long-distance contribution of a penguin diagram involving up quarks. The penguin contribution is expected to be comparable in size to the precision of the LHCb and Belle II experiments and, therefore, limits the sensitivity of the m...

Background: The sub-Antarctic Prince Edward Archipelago (46°53’S, 37°52’E), consisting of Marion and Prince Edward islands, is situated in the Indian sector of the Southern Ocean, approximately 2 600 km away from the closest Adélie penguin (Pygoscelis adeliae) breeding locality, Bouvet Island (54°25’S; 3°22’E). Methods: Two opportunistic sightings of an Adélie penguin at Marion Island on 28 Oct...

Performing a fit to the available experimental data, we quantify the effect of long-distance contributions from penguin contractions in B0 → J/ψK0 decays. We estimate the deviation of the measured SCP term of the time-dependent CP asymmetry from sin 2β induced by these contributions and by the penguin operators. We find ∆S = 0.000±0.017 ([−0.035, 0.033] @ 95% probability).

Two-body charmless nonleptonic decays of the Bs meson are studied within the framework of generalized factorization in which factorization is applied to the tree level matrix elements while the effective Wilson coefficients are μ and renormalization scheme independent, and nonfactorizable effects are parametrized in terms of N eff c (LL) and N eff c (LR), the effective numbers of colors arising...

The Falkland Islands are an important breeding site for three species of penguin, gentoo (Pygoscelis papua), southern rockhopper (Eudyptes c. chrysocome) and Magellanic penguin (Spheniscus magellanicus). The total penguin population for the Falkland Islands has declined by 84 % during the 1980s and 1990s. These declines did not occur in coastal South America, so potential causes of decline in t...

Rare loop-induced decays are sensitive to New Physics in many Standard Model extensions. In this paper we discuss the potential of the LHCb experiment to very rare Bs → μ μ decays, radiative penguin b → sγ decays and electroweak penguin b → sll decays. The experimental strategies and the expected sensitivities are presented. PACS. PACS-key 14.40.Nd – PACS-key 12.60.-i
