Aria Basirnia (Rutgers University)04/05/2015, 16:30parallel talkWe present a new mechanism to generate large A-terms at tree-level in the MSSM through the use of superpotential operators. The mechanism trivially resolves the A/m^2 problem which plagues models with conventional, loop-induced A-terms. We study both MFV and non-MFV models; in the former, naturalness motivates us to construct a UV completion using Seiberg duality. Finally, we study the...Go to contribution page

Carlos Alvarado (University of Notre Dame)04/05/2015, 16:45parallel talkWe explore extensions of the Minimal Supersymmetric Standard Model involving two SU(2)L triplet superfields that share a superpotential Dirac mass yet only one of which couples to the Higgs fields. This choice is motivated by recent work using two singlet superfields with the same superpotential requirements. We find that, as in the singlet case, the Higgs mass in the triplet extension can be...Go to contribution page

Michael Savoy04/05/2015, 17:00parallel talkRecently, it has been argued that various measures of SUSY naturalness- electroweak, Higgs mass and EENZ/BG- when applied consistently concur with one another and make very specic predictions for natural supersymmetric spectra. Highly natural spectra are characterized by light higgsinos with mass not too far from m_h and well-mixed, but TeV- scale, third generation squarks. We apply the...Go to contribution page

Jeff Dror (Cornell University)04/05/2015, 17:15parallel talkThe LHC collaborations are putting forth tremendous efforts to find supersymmetry at the TeV scale. However, they are yet to find any conclusive hints of physics beyond the Standard Model. Meanwhile, both ATLAS and CMS have discovered a new scalar at 125 GeV which appears compatible with the Standard Model Higgs. Recently, the possibility that the Higg's doublet is the superpartner of one of...Go to contribution page

Yousuke Kataoka (University of Tokyo (JP))04/05/2015, 17:30SUSYparallel talkDespite 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 searches for supersymmetric squarks and gluinos, including third generation squarks produced directly or via decay of gluinos, using 20/fb of sqrt(s)=8 TeV p-p collision data. The searches involved...Go to contribution page

Sunghoon Jung04/05/2015, 17:45parallel talkWe derive new limits on light stops using resonance searches in the channels of diphoton, Z+photon, WW, ZZ and hh. Remarkably, we find that stoponium searches are highly complementary to direct collider searches as well as indirect probes such as Higgs coupling measurements and electroweak precision test. The diphoton is most complementary as it is maximally sensitive when the Higgs-stop-stop...Go to contribution page

Preema Rennee Pais (University of Massachusetts (US))04/05/2015, 18:00SUSYThis talk presents the latest ATLAS results in the context of electroweak production of SUSY particle, R-Parity violating SUSY scenarios, and scenarios with long-lived SUSY particles. The results presented use the full 20/fb of sqrt(s)=8TeV p-p collisions collected by the ATLAS experiment in 2012. The prompt searches consider final states including leptons, jets (including b-jets) and missing...Go to contribution page

Samuel Louis Bein (Florida State University (US))04/05/2015, 18:15SUSYparallel talkThe R-parity conserving minimal supersymmetric Standard Model (MSSM) is a possible description of nature that is motivated by its providing a natural explanation for the hierarchy problem and a possible account of cosmic dark matter. The vastness of the full model space of the MSSM, which spans over 100 dimensions, has motivated the interpretation of CMS results in terms of a proxy model for...Go to contribution page
