Recent results from the Tevatron will be reported
on Higgs searches in models beyond the Standard Model.
The models include fermiophobic Higgs bosons,
the extension of the Standard Model to a 4th
generation of fermions and supersymmetric scenarios.

We present the most recent $W$ and $Z$ production, asymmetries, and $V$+jets results from the Tevatron collider at $\sqrt{s}$ = 1.96 TeV, analyzing data collected by CDF and DZero detectors between 2002-2011. The results include the measurements of the $W$ and $Z$ bosons properties, include boson $p_T$ and asymmetries measurements, and also the $W$ and $Z$ boson plus jets productions. Those...

Highlights of ATLAS and CMS measurements involving the production of heavy electroweak gauge bosons, W and Z, at the LHC will be presented. Cross sections of single W and Z bosons are studied with very high precision and differential in various kinematic variables. The
rapidity differential measurements are shown to have a so far unique impact on our knowledge of proton structure with regards...

Noncommutative geometry (NCG) allows to unify the basic building blocks of particle physics, Yang-Mills-Higgs theory and General relativity, into a single geometrical framework. The resulting effective theory constrains the couplings of the Standard Model (SM) and reduces the number of degrees of freedom.
After briefly introducing the basic ideas of NCG, I will present its predictions for...

We present an overview of the recent results on the production of massive boson pairs in p-pbar collisions at a center-of-mass energy of 1.96 TeV, studied by the CDF and D0 experiments at the Tevatron. The measurements performed are a precise test of the Standard Model and crucial backgrounds for several different searches for new physics. In particular the good knowledge of the diboson...

Brane SUSY Breaking is a peculiar phenomenon that has emerged from the study of orientifold models in String Theory. It occurs whenever the vacuum is to contain different collections of BPS branes whose simultaneous presence breaks supersymmetry at the string scale. It leaves behind scalar fields with exponential potentials that could have injected the inflationary phase of our Universe and...

The MEG experiment at PSI is searching for the possible lepton flavor violating decay of a muon into an electron and a positron with unprecedented sensitivity.
The existence of this decay would represent an unambiguous sign of new physics beyond the Standard Model. The current best world upper limit of 2.4 x 10**(-12) on the branching ratio of the mu->e gamma decay was published by MEG in...

The neutral and charged current deep inelastic ep scattering, with longitudinally polarised lepton beams, have been studied with the H1 and ZEUS detectors at HERA. The differential cross sections are measured in the range of four-momentum transfer squared, Q2 , up to 50'000 GeV2, where electroweak effects become clearly visible. The measurements are used to determine the structure function...

Measurements of the muon magnetic anomaly performed at the BNL have reached an accuracy of 0.54 ppm and the final result differs from Standard Model estimates by 3.2-3.6 standard deviations. The main uncertainty on the theoretical evaluation is due to hadronic loop contributions which are not calculable in perturbative QCD and are obtained from a dispersion integral over the hadronic cross...
