137. Introducing SuperLFV, an SLHA Tool

Prof. Brandon Murakami (Rhode Island College)

06/05/2013, 16:30

parallel talk

We introduce SuperLFV, a numerical tool for calculating low-energy observables that exhibit charged lepton flavor violation (LFV) in the context of the minimal supersymmetric standard model (MSSM). As the Large Hadron Collider and MEG, a dedicated mu -> e gamma experiment, are presently analyzing or acquiring data, there is need for tools that provide rapid discrimination of models that...

153. Squark Pair Production at NLO

Eva Popenda (P)

parallel talk

A lot of effort is and will be put in the search for supersymmetric particles at the LHC. For the interpretation of the experimental data precise theoretical predictions are crucial. The work presented in the talk contributes to this effort by providing NLO corrections to the pair production of squarks of the first two generations in a flexible partonic Monte Carlo program. In contrast to...

116. Squark Pair Production in the POWHEG Box

Ryan Gavin (Paul Scherrer Institut)

parallel talk

The search for supersymmetry is an important part of the LHC physics program. For these searches, precise predictions are needed and including parton showers can improve these predictions. Squark pair production at NLO matched to a parton shower using the POWHEG Box will be presented.

100. Searches for squarks and gluinos with the ATLAS detector

Amir Farbin (University of Texas at Arlington (US))

parallel talk

Despite the absence of experimental evidence, weak scale supersymmetry remains one of the best motivated and studied Standard Model extensions. This talk summarises recent ATLAS results on inclusive searches for supersymmetric squarks and gluinos in events containing jets, missing transverse momentum with and without light leptons, taus or photons.

50. Same sign dibosons from SUSY models with light higgsinos at the LHC

Azar Mustafayev (U)

parallel talk

In supersymmetric models with light higgsinos (which are motivated by electroweak naturalness arguments), the direct production of higgsino pairs may be difficult to search for at LHC due to the low visible energy release from their decays. However, the wino pair production reaction also occurs at substantial rates and leads to final states including equally opposite-sign (OS) and same-sign...

65. Searches for electroweak production of supersymmetric neutralinos, charginos and sleptons with the ATLAS detector

Per Johansson (University of Sheffield (GB))

06/05/2013, 17:45

parallel talk

Many supersymmetry models feature neutralinos, charginos and also sleptons with masses less than a few hundred GeV. These can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded by the ATLAS detector. The talk presents results from searches for neutralinos, charginos and slepton pair production in final states with leptons.

87. Multilepton Signals of Composite MSSM

Rachel Houtz (UC Davis)

06/05/2013, 18:00

parallel talk

While SUSY is becoming more constrained by recent data from the LHC, there is still hope for SUSY in light stop scenarios. The Minimal composite Supersymmetric Standard Model is one such scenario. We examine the potential for discovery of such models at the LHC using a set of benchmark spectra associated with UV complete models within the McSSM.

72. Sleptons to the Rescue

Dr David Curtin (Stony Brook University)

06/05/2013, 18:15

parallel talk

Recent measurements of the WW cross section by ATLAS and CMS are slightly above SM expectations, leaving the possibility for BSM electroweak states to contribute to the measurements. We show how light sleptons with bino dark matter can account for the WW measurment as well as muon g-2 while achieving the correct dark matter relic density.
