A large number of cosmic events were recorded during 2009 and 2010 for the calibration, alignment and commissioning of most of the ALICE (A Large Ion Collider Experiment at the CERN LHC) detectors. New cosmic data are continuously taken in 2011 during the periods in which the LHC accelerator does not produce any beam. Specific triggers, not used during the LHC collisions, were implemented to take

Supersymmetric models predict the existence of light neutralinos with masses around 50 GeV as good candidates for detection of physics beyond the standard model, as well as other supersymmetric particles to different channels of decay of the Higgs bosons. In this work, we present the branching ratios of lightest Higgs boson to neutralinos and charginos in the context to MSSM. Then, it is determin

Flavor violating $tu_iH$ vertex induces top quark couplings $tc\gamma$
and $tu_i\gamma \gamma$ ($u_i=u,c$) at the one-loop level, in the effective Yukawa
sector through dimension six $SU_L(2)\times U_Y(1)$-invariant operators. The $t\to
cH$ and $t\to c\gamma \gamma$ decays can reach branching ratios about $5\times
10^{-3}$ and $10^{-4}$, respectively. As for $tc$ production, it is found that

The information gathered in the E318 Focus experiment provides a spin polarization
parameter measured for the p + K(short) channel. The measurement consists on fitting
the angular distribution of the generation of the kaon, in the frame of the Lambda C
propagation plane (with the original photon). The study involves the signal
enhancement and angular distribution for particles and antiparticle

In the framework of the two Higgs Doublet Model we graphically illustrate the energy dependence of the Higgs masses and the quartic couplings. Our results are based on the theoretical constraints on the quartic Higgs couplings through the stability and triviality principles that are obtained, using the Lagrange multipliers method and the numerical solutions of the Renormalization Group Equations,

The study of the phenomenology of an extra neutral gauge boson, Z_H, can give hints of the details of the model from which it arises. We study the decay of such a particle into two neutral gauge bosons, Z_H-> V_i Z (V_i = γ,Z), in two popular versions of the little Higgs model: the littlest Higgs model (LHM) and the simplest little Higgs model (SLHM). These decays are induced at the one-loop leve

With the data from CDF at an integrated luminosity of 6fb−1, we study the same sign
dimuon events in the low mass spectra (below 5GeV) with Pt > 8GeV. Upon applying
tight identification cuts on the leading muon and loose identification cuts in the
second, when reconstructing the muons’ mass, an increased number of events remains
below 5 GeV (for the pre-stripped data from CDFPEWK) at

The study of the tau lepton physics plays a significant role in the present accelerator program. Due to the great variety of the tau decay channels, its phenomenology offers an interesting scenario to search for potential effects of new physics. In particular, the tau weak moments remain unexplored beyond the standard model (SM), which predicts negligible values for these properties. This opens

We perform a MC simulation of a system consisting of two quarks and two antiquarks, Using a dynamical model of the strong interaction we explore the formation of mesons and/or tetraquark for a set of different density conditions.
We characterize the single properties of these states and the modifications upon the mixing. The competition among the different configurations and its implications on
