Long-distance contribution to the muon-polarization asymmetry in K^+\to π^+ μμ

Giancarlo D'Ambrosio, Dao-Neng Gao

We revisit the calculation of the long-distance contribution to the muon-polarization asymmetry Δ_{LR}, which arises, in K^+\toπ^+μ^+μ^-, from the two-photon intermediate state. Th…

Radiative rare kaon decays

Giancarlo D'Ambrosio

We discuss theoretical issues in radiative rare kaon decays. The interest is twofold: to extract useful short-distance information and understand the underlying dynamics. We emphas…

Charming penguin contributions to charmless B decays into two pseudoscalar mesons

C. Isola, M. Ladisa, G. Nardulli +2

We present estimates of the charming penguin contribution to B => K pi, pi pi,K eta, K eta' decays due to intermediate charmed meson states. We find that this contribution is indee…

Neutrino Oscillations in Caianiello's Quantum Geometry Model

V. Bozza, S. Capozziello, G. Lambiase +1

Neutrino flavor oscillations are analyzed in the framework of Quantum Geometry model proposed by Caianiello. In particular, we analyze the consequences of the model for accelerated…

The diquark model: New Physics effects for charm and kaon decays

Giancarlo D'Ambrosio, Dao-Neng Gao

Motivated by diquark exchange, we construct a class of extensions of the standard model. These models can generate large CP conserving and CP violating contributions to the doubly…

Absolute determination of D_s branching ratios and f_{D_s} extraction at a neutrino factory

G. De Lellis, P. Migliozzi, P. Zucchelli

A method for a direct measurement of the exclusive D_s branching ratios and of the decay constant f_{D_s} with a systematical error better than 5% is presented. The approach is bas…

Bose Einstein condensation at reheating

G. Mangano, G. Miele, S. Pastor +1

We discuss the possibility that a perturbative reheating stage after inflation produces a scalar particle gas in a Bose condensate state, emphasizing the possible cosmological role…

Charming penguin contributions to B => K π

C. Isola, M. Ladisa, G. Nardulli +2

We present calculations of the charming-penguin long-distance contributions to B => K πdecays due to intermediate charmed meson states. Our calculation is based on the Chiral Effec…
