25. Rare B decays including EW, leptonic and hadronic-penguin decays

CP Violation: CKM and Beyond

Rare decays, i.e. decays that are expected to have very small branching fractions, are sensitive to new physics beyond the Standard Model. The large samples of BB-bar pairs accumulated at the B factories provide good opportunities to measure such decay modes. We present a review of recent measurements including hadronic- electroweak-penguin decays, as well as leptonic decays.

45. Study of the eta--pi+ pi- e+ e- decay at KLOE

CP Violation: CKM and Beyond

The KLOE experiment has concluded its data taking in March 2006, having acquired an integrated luminosity of 2.5 fb-1 of e+e- collisions at the center of mass energy around the phi(1020) resonance. The complete data set includes a sample of 100 million eta's produced through the radiative decay phi --> eta gamma and tagged by means of the monochromatic recoil photon. This huge amount...

60. Vus and CP invariance test from Kaon decays with the KLOE detector

CP Violation: CKM and Beyond

The KLOE experiment has provided precise measurements of the branching ratio of the main neutral and charged kaon decay modes, of the $K_L$ and the $K^{\pm}$ lifetimes, and of the $K_L$ vector and scalar form factors. We present a description of the above measurements and an overall fit of all our data, with particular attention to correlations. These data provide the basis for the...

99. SUSY contributions to Phi_Bs from highly non-degenerate sfermions

Supersymmetry

We reconsider the mass insertion approximation in the limit in which the sfermions are highly non-degenerate. We show that the correlation between the supersymmetric contributions to Delta F = 1 and Delta F = 2 observables strongly depends on the sfermion spectrum. In particular, we show that larger contributions to the phase of the Bs mixing amplitude are allowed in the non-degenerate case.

2. The QED corrections in the Standard Model

The radiative correction (of the type g/2pi) is one of the commonly used methods of a comparison of the effects with very different scales [1]. For example, Bernstein marked the closeness of the QED correction (alpha/pi) to the parameter of CP-nonconservation in kaon decay [2]. There is an exact coincidence between QED radiative correction alpha/2pi=1.159 10-3 with the ratio between...
