We investigate the problem of identifying ντ-induced reactions in large neutrino telescopes. We concentrate on events with tracks and showers where the respective energies Eμ and EX are measured separately. Then we compute analytically and numeric

Neutral gauge bosons beyond the Standard Model are becoming interesting as possible mediators to explain several experimental anomalies. They have small masses, below one GeV, and are referred to as dark photons, $U$, $A'$ or $Z'$ bosons. Electron--p

We present a new analysis for coherent pion production on nuclei relevant for the energies available at K2K, MiniBoone and Minos. This work is based on two new contributions. (1) The realization and demonstration that coherent pion production takes p

Nuclear corrections are presented for neutrino and electron induced reactions in a pedagogical manner. The formalism is demonstrated with numerical studies and is shown to produce substantial corrections in channels where the pions have the same char

We rederive the t-quark condensate model by a method in which the Goldstone and Wigner modes of the theory are coexistent. The basic motivation is to avoid any specific form of the interaction at high energy Λ, except for the fine-tuning hypothesis

We present a recent analysis of epsilon'/epsilon in the 1/N_c expansion. We show that the 1/N_c corrections to the matrix element of Q_6 are large and positive, indicating a Delta I=1/2 enhancement similar to the one of Q_1 and Q_2 which dominate the

We present a new analysis of the ratio ε^'/ε which measures the direct CP violation in K→ππ decays. We use the 1/N_c expansion within the framework of the effective chiral lagrangian for pseudoscalar mesons. The 1/N_c corrections to the hadroni

We give precise values for the elements of the flavor mixing matrix and the CP-violating phase, then study their dependence on the unknown dynamical parameters, like the bag factor, QCD corrections, mass of the top quark,… We estimate the mixing pr
