Abstract:
As the LHC prepares to transition into the high luminosity era, LHC experiments have intensified their efforts to achieve maximal experimental coverage in the search for physics beyond the standard model. This presentation highlights two recent innovative searches within the framework of R-Parity violating supersymmetry at the LHC, featuring complementary final states characterized by enhanced jet activity in proton-proton collisions. The first search, conducted by ATLAS, investigates the strong production of gluinos that decay into triplets/quintuplets of quarks, resulting in all-hadronic multijet signatures. The second search, carried out by CMS, focuses on the electroweak production and cascade decays of superpartners, leading to final states with multijets as well as W and Z bosons. Various novel data-driven techniques are employed to address the challenges posed by hadronic signatures. In this talk, we will provide a brief theoretical and experimental overview of the state-of-the-art at the LHC, followed by an in-depth discussion of the analyses.
Halil Saka (CMS) is an assistant professor at University of Cyprus, pursuing a research program on a diverse set of signals with leptonic signatures, such as heavy fermions, leptoquarks, light spin-0 particles in extended Higgs sector models, as well as R-parity violating supersymmetric models. He received his PhD from Princeton University in 2015 working on third generation leptoquarks, and subsequently held a post-doctoral associate position at Rutgers University focusing on inclusive searches for beyond the standard model physics in multilepton final states. Halil has previously served as co-convener of the EXO Non-hadronic and SUS Leptonic+RPV Working Groups, as well as in various positions regarding the operations and upgrades of the CMS Hadron Calorimeter subdetector.
Anthony Badea (ATLAS) is a research fellow at the University of Chicago. He received his Ph.D. from Harvard University in 2023 and B.S. from MIT in 2019. He’s worked on small system collectivity with e+e- collisions in connection to heavy ion physics, searches for beyond the standard model physics in all hadronic final states of pp collisions, and currently top quark production in PbPb collisions. For hardware, he helped commission the ATLAS New Small Wheel micromegas detector and is currently working on ASIC R&D for on-chip machine learning at future smart detectors. Broadly, he is interested in understanding the dynamics of the early universe, including the electroweak and QCD phase diagrams probable at current and future accelerator facilities.
