The ANTARES collaboration completed in 2008 the construction of the largest neutrino telescope in the Northern hemisphere. Neutrinos, being neutral, stable and weakly-interacting have unique advantages with respect to other more traditional probes to study the high energy Universe. The scientific scope of ANTARES is very broad, including the observation of astrophysical neutrino sources, the...

Super-Kamiokande started its operation in 1996. Since then, more than 3000 days of atmospheric neutrino data has been collected. In the beginning, we have obtained \Delta_m^2_{23} and \theta_{23} with two flavor oscillation using the zenith angle distirbution of observed leptons. Afterwards, we have extracted L/E distribution from observed quantities to deduce the oscillation parameters....

EGADS (Evaluating Gadolinium's Action on Detector Systems) is a test facility for a new neutrino detection method using a gadolinium-loaded water Cherenkov detector. In this method, events due to anti-neutrino charged-current interactions on protons (i.e., inverse beta decay) are identified by the coincident detection of a prompt positron signal and a delayed gamma-ray signal from neutron...

Recent results of the Super-Kamiokande (SK) solar neutrino measurements are presented. The main goal of SK's solar analysis is to observe the MSW effect, i.e. a solar neutrino energy spectrum distortion induced by matter in the Sun, and a day/night solar neutrino flux asymmetry induced by matter in the Earth.
Thanks to the improvement of the detector's water circulation system, low energy...

Results from reactor neutrino experiments show a repeating pattern of a small constant deficit at baselines between 16 m and 1-2 km as described in the paper by Mention et al. Proposed explanation of the deficit is so called reactor neutrino anomaly that requires existence of a non-standard neutrino oscillation with a very short baseline. Convincing independent confirmation of this result can...

A combination of the inclusive diffractive cross section measurements made by the H1 and ZEUS Collaborations at HERA is presented. The analysis uses diffractive deep inelastic scattering data measured by means of proton spectrometers. Correlations of systematic uncertainties are taken into account by the combination method, resulting in improved precision. The combined data cover the range 2.5...

The TOTEM experiment recently measured the elastic proton rates dN/dt down to โt=0.02 GeV^2 at the LHC energy of \sqrt s = 7 TeV. In addition, the accompanying inelastic rates were recorded with the forward telescopes for 5.3 < |eta| < 6.4. The optical theorem allowed for first luminosity independent total cross-section measurement at \sqrt s = 7 TeV energy. Moreover, the total pp...

Due to its unique pseudorapidity coverage and the possibility of extending the measurements to low transverse momenta, LHCb provides important input to the understanding of particle production and energy flow in a kinematical range where QCD models have large uncertainties. Measurements of charged, strange and charmed particle production are compared to predictions. In addition, studies of...

The mechanism of production of heavy-flavoured mesons, containing b or c quarks, in association with vector bosons, W or Z, in the Standard Model is only partially understood. The study of events with one or two well-identified and isolated leptons accompanied by b-jets or secondary vertices is therefore crucial to refine the theoretical calculations in perturbative QCD, as well as validate...
