Prashant Saraswat (University of Maryland and Johns Hopkins University)06/05/2014, 14:00Supersymmetry is under pressure from LHC searches requiring colored superpartners to be heavy. We demonstrate R-parity violating spectra for which the dominant signatures are not currently well searched for at the LHC. In such cases, the bounds can be as low as 800 GeV on both squarks and gluinos. We demonstrate that there are nontrivial constraints on squark and gluino masses with baryonic...Go to contribution page

Allan Kenneth Lehan (University of Liverpool (GB))06/05/2014, 14:15An extended QCD sector beyond the minimal supersymmetric standard model or the admission of R-parity violation introduces new signatures to the search for supersymmetry at the LHC. Strongly interacting resonances may decay to jets, sleptons may decay via lepton-flavour violating processes and lightest supersymmetric particles may decay into many leptons with or without missing transverse...Go to contribution page

Bob Zheng (University of Michigan)06/05/2014, 14:30It is commonly stated that in R-parity violating supersymmetric models, the simultaneous presence of renormalizable B and L-violating interactions is heavily constrained as they induce 2-body proton decay. In this talk, I will point out that certain LLE couplings which are anti-symmetric in flavor indices will instead induce 4-body proton decay when combined with UDD couplings. The resulting...Go to contribution page

Kevin Pedro (University of Maryland (US))06/05/2014, 14:45We present the search for 3rd generation leptoquark pair production, with decays to pairs of b+tau as well as pairs of top+tau. The searches are also re-interpreted in terms of R-parity violating stop squark decays with LQD couplings.Go to contribution page

Jamie Tattersall (University of Heidelberg)06/05/2014, 15:00In the first three years of running, the LHC has delivered a wealth of new data that is now being analysed. With over 20 $fb^{−1}$ of integrated luminosity, both ATLAS and CMS have performed many searches for new physics that theorists are eager to test their model against. However, tuning the detector simulations, understanding the particular analysis details and interpreting the results can...Go to contribution page

Peter Schichtel (Heidelberg University)06/05/2014, 15:15The Neyman-Pearson lemma states that the likelihood-ratio is the most powerful estimator for hyposthesis testing. Given a signal and a background model our tool MadMax computes the log-likelihood distributions of the signal and background hypotheses for a given luminosity at the LHC. From these we calculate the corresponding gaussian significance to quantify the distance of the two hypotheses....Go to contribution page

James Gainer (University of Florida (US))06/05/2014, 15:30The Matrix Element Method (MEM) has become an important tool in experimental particle physics, as it provides optimal sensitivity in using data to distinguish between models that could explain that data. However, it has generally required some concrete model to describe the potential signal. Motivated by the possibility of surprises at the Large Hadron Collider (LHC), we develop a MEM-based...Go to contribution page

Prof. Joel Walker (Sam Houston State University)06/05/2014, 15:45The AEACuS (Algorithmic Event Arbiter and Cut Selector) computer program has been developed as a lightweight consumer-level tool for implementing generic collider data selection cuts in the search for new physics. The compact and powerful meta language invented to control the operation of this program is suggested as a potential standard for the unambiguous communication of various event...Go to contribution page
