The reconstruction of $K^0_S$ and $\Lambda$ resonances is a crucial test
of the performance of the LHCb tracking detectors, the reconstruction
software and the status of the alignment of the LHCb spectrometer.
We will present first results towards a measurement of the V0 production
rate based on data taken at a center of mass energy of 900GeV in December
2009 with the LHCb experiment.

The workflow of the measurement of the Jpsi cross section in the di-muon decay channel with CMS at the LHC will be given, with a particular emphasis in the description of the determination of the muon detection efficiency and acceptance.

The study of the production of two Z bosons at the TeV scale constitutes an important test of the Standard Model and it is a necessary step towards the discovery of new physics and new particles like the Higgs boson. We investigate the CMS potential for the observation and study of pp-> ZZ->4l reaction at LHC center of mass energies, using fully simulated signal and background samples. It is...

The search for the Higgs boson will be one of the main issues in the next year in the ATLAS detector. The H->ZZ*->4e channel in particular, is a very promizing channel to discover the Higgs for masses above 130 GeV with a clean electron signal. The electron reconstruction and identification plays here a key role. Since the CSC note published 2 years ago a lot of work as been done in order to...

The search for physics beyond the Standard Model (BSM) is one of the most important goals for the general purpose detector ATLAS at the Large Hadron Collider at CERN. Already with early LHC data, the ATLAS experiment should be sensitive to discover physics beyond the Standard Model. In this talk I summarize the prospects of the ATLAS experiment to find experimental evidence for Supersymmetry...

Using a effective Lagrangian approach we show how the bounds to the new operators that come from high energy data can be improved with the inclusion of the experimental information of the CKM-universality, a low energy observable. We assume U(3)^5 invariance, although some remarks will be done about the general case, with non-U(3)^5 invariant operators.

Several key measurements of the LHCb experiment rely on the efficient identification of muons. Examples of these are the search for the rare decay Bs->mumu and the study of the angular distributions of the decay B0>K*mumu. A summary of the LHCb muon identification strategy is presented, covering both the baseline method, and also alternative approaches presently under development. First...

We study sensitivity to the non-standard interaction in neutrino
propagation of the T2KK neutrino long baseline experiment, assuming
only the non-zero electron and tau neutrino components epsilon_{ee},
epsilon_{e tau}, epsilon_{tau tau} of the non-standard matter effect,
and taking into account the atmospheric neutrino constraint on these
parameters. We found that T2KK can restrict the...

Low energy supersymmetry can be theoretically motivated as a solution to the hierarchy problem of the Standard Model if the superpartner states are not too heavy. The non-observation of SUSY and precision tests then introduces some tension in the attempt for naturalness. I will present a study of the amount of fine tuning at 2-loop order in the constrained MSSM and discuss which regions of the...
