We investigate the consequences at low energies of a new MSSM-SU(5) induced symmetry relation in the up-squark sector. We show that this relation is not too much spoiled by the RGE running down to the electroweak scale and is kept relatively model independent. Therefore, it could bring us information on the possibility that a SU(5) symmetry holds at high energies assuming that the LHC will...

The measurement of the electroweak production cross section of a Z-boson in association with two jets in proton-proton collisions by the CMS experiment is presented. The cross section is measured in dielectron and dimuon final states and the measurement, combining different methods and channels is in agreement with the theory prediction.The hadronic activity in events with Z-boson production...

With new results and limits on constrained models of supersymmetry (SUSY) from the ATLAS and CMS collaborations at the LHC, questions arise about what these limits imply for more general models of SUSY or other models for physics beyond the Standard Model. Since SUSY has a vast array of parameters, both collaborations also quantify their search results in terms of simplified models, augmenting...

Some models beyond the Standard Model (BSM) suggest that the Higgs boson, discovered at the LHC during run I, can be used as a portal to look for New Physics. These models predict new sectors coupled to the SM whose presence can be inferred by observing SM final states. This opens the possibility of processes such as Higgs decays to dark vector bosons in four-leptons events, $H\rightarrow...

The high center-of-mass energy of the $pp$ collisions at the LHC enables searches for new particles with masses at the TeV scale. These heavy resonances can decay to final states with high $p_{\rm T}$ $W$- and $Z$-bosons. The hadronic decay modes of these bosons are of special interest of the potential increase in sensitivity for measurements and searches. However the cross-section of...

We present a measurement of the distribution of the variable \phi_{\eta}* for muon pairs with masses between 30 and 500 GeV, using the complete Run II data set collected by the D0 detector at the Fermilab Tevatron proton-antiproton collider. This corresponds to an integrated luminosity of 10.4 fb^{−1} at \sqrt{s}= 1.96 TeV. The data are corrected for detector effects and presented in bins of...

Since the main experimentally testable prediction of grand unified theories is the instability of the proton, precise determination of the proton lifetime for each particular model is desirable. Unfortunately, the corresponding computation usually involves theoretical uncertainties coming e.g. from ignorance of the mass spectrum or from the Planck-suppressed higher-dimensional operators, which...
