Presentazione
ARGO-YBJ is an RPC "carpet" aimed to the detection of extensive air showers induced by charged cosmic rays and gamma-rays in the energy range GeV-PeV. The experiment obtained important results in cosmic-ray physics and gamma-ray astronomy. In the 300 GeV - 10 TeV energy range it is operated in "shower mode" and a good reconstruction of the primary arrival direction is performed within the...

A combination is presented of the inclusive diffractive cross section measurements made by the H1 and ZEUS collaborations at HERA. The analysis uses all available diffractive deep inelastic scattering data, ep -> eXp, recorded between 1997 and 2007 and selected with the Large Rapidity Gap technique. Correlations of systematic uncertainties are taken into account by the combination method,...

The LHCb experiment is designed to perform flavour physics measurements at the Large Hadron Collider. Using data collected during the 2010 run, we reconstructed a sample of Hb --> h+h'- decays, where Hb can be either a B0 meson, a Bs0 meson or a Lambda_b baryon, while h and h? stand for pi, K or p. Such decays are sensitive probes of the Cabibbo-Kobayashi-Maskawa matrix and have the potential...

The V-A nature of the electroweak current leads to an asymmetry in the polar angle distribution in the rest frame of Z/gamma*: the measurement of such a quantity, around Z pole, can provide a precise determination of the weak mixing angle of the Standard Model. In this contribution the asymmetry measurement in the muon channel will be presented with the data collected by the ATLAS experiment...
