X02.00001: Long-lived Particles at the LHC Invited Speaker: Jessie Shelton Long-lived particles (LLPs) present both a major opportunity and a major challenge at the LHC. On one hand, the backgrounds for displaced objects are inherently small, in many cases making prospects for displaced signals much better than for otherwise similar prompt signals. On the other hand, searches for LLPs are particularly challenging as they demand specialized reconstruction algorithms, and, since they involve aspects of detector response which cannot be reliably simulated with public tools, are notoriously di cult for theorists to accurately apply to new models. I will discuss theoretical motivations for LLPs, new ideas for searches, and the great opportunities and challenges offered by LHC Run 2 and beyond. [Preview Abstract] |

X02.00002: Higgs physics at LHC Invited Speaker: Swagato Banerjee The most recent results for Higgs physics in proton-proton collisions at the LHC will be reviewed in this talk. Many precision measurements involving the coupling and mass of Higgs boson have been performed by the ATLAS and CMS experiments in a wide range of final states. The measurements presented provide important constraints on models beyond the Standard Model. [Preview Abstract] |

X02.00003: Beyond Standard Model physics at the Large Hadron Collider Invited Speaker: Sunil Somalwar The Higgs boson, discovered at the Large Hadron Collider, completed the Standard Model puzzle. However, we still cannot explain why the Higgs boson is as light as it is. Nor can we explain the evolution of the nascent universe right after its big bang birth. That is when matter and anti-matter almost entirely annihilated each other, leaving behind an exceedingly small excess of matter that makes up our world today. The Large Hadron Collider addresses these questions by taking us back all the way to 10-100 picoseconds after the big bang. LHC's treasure-trove of proton-proton collision data could allow us to better understand the mysteries of the nascent universe and the Higgs mass. I will describe how the ATLAS and CMS experiments at the LHC are using this data to confront novel theories that go Beyond Standard Model to explain these mysteries. [Preview Abstract] |
