Prospects for non-standard SUSY searches at LHC

New studies of the ATLAS and CMS collaborations are presented on the sensitivity to searches for non-standard signatures of particular SUSY scenarios. These signatures include non-pointing photons, as well as pairs of prompt photons, as expected in GMSB SUSY models, as well as heavy stable charged particles produced in split supersymmetry models, long lived staus from GMSB SUSY and long lived stops in other SUSY scenarios. A detailed detector simulation is used for the study, and all relevant Standard Model backgrounds and detector effects that can mimic these special signatures are included. It is shown that already with less than 100 pb$^{-1}$ the ATLAS and CMS sensitivity will probe an interesting as yet by data unexplored parameter range of these models.Comment: Paraller talk presented at ICHEP08 on behalf of the ATLAS and CMS Collaboration

Bottomonium production at forward rapidity with ALICE at the LHC

Bottomonium production is a powerful tool to investigate hadron collisions and the properties of the medium created in heavy-ion collisions. According to the color-screening model, these mesons give important information about the deconfined medium called Quark-Gluon Plasma (QGP) produced in ultrarelativistic heavy-ion collisions. Cold nuclear matter (CNM) effects can modify the bottomonium production even in absence of deconfined matter: the study of proton-nucleus collisions is therefore essential to disentangle these effects from the hot ones. Last but not least, measurement in pp collisions serve as crucial test of different QCD models of quarkonium hadroproduction and provide the reference for the study in nucleus-nucleus collisions. In ALICE, bottomonium is measured at forward rapidity ($2.5 < y < 4$) down to zero transverse momentum, exploiting the dimuon decay channel. The latest results in pp, Pb-Pb and p-Pb collisions are discussed and compared to theoretical calculations.Comment: Proceeding of the presentation at the Initial Stages 2014 Conference, Napa, 3-7 December 201

SUSY sensitivity in final states with leptons, jets, and missing transverse energy

Final states with leptons, jets and missing transverse energy are a promising way to detect Supersymmetry at the Large Hadron Collider. Results of simulation studies performed by the CMS and ATLAS collaborations are presented. The discovery of new physics is shown to be possible within the first fb^-1 of collected integrated luminosity.Comment: Submitted for the SUSY07 proceedings, 4 pages, LaTeX, 6 eps figure
