Innovating Triggers and Triggering Innovation: Illuminating New Physics at the Energy Frontier

Abstract:Although no new fundamental particles have been observed since the 2012 discovery of the Higgs boson, many compelling theories beyond the Standard Model (BSM) predict new physics at the electroweak or TeV scales accessible to the LHC. The absence of significant excesses underscores the imperative to expand sensitivity to uncovered and unexplored regions of phase space. This talk will focus on leveraging novel trigger techniques and creative reconstruction methods — both present and future — to maximize the discovery potential of long-lived particles and other anomalous BSM physics signatures at the CMS experiment. These efforts will be examined in the context of the LHC, the High-Luminosity LHC, and long-term planning for the future of collider-driven science.

Nucleons: Crossing the Bridge from Quarks to Nuclei

Abstract:
Physicists seek to answer the fundamental question: How is the nucleus of an atom held together to build the matter we see? In the lower energy picture, we describe the nucleus in terms of its protons and neutrons and their exchange of mesons. In the higher energy picture, composite protons and neutrons (composed of quarks and gluons) interact through quantum chromodynamics (QCD). This residual interaction is the strong nuclear force. Through QCD we can describe the proton as a superposition of quark-gluon states that can include states of different sizes. This description naturally implies that bound protons can be different from free protons and allows for color transparency phenomena (whereby the constituent quarks are in a smaller-sized configuration). Using the high intensity electron beam at Jefferson Lab, we study the connection between these descriptions in order to understand how the strong force binds the nucleus together. This talk will discuss insights and future directions using nuclei as a laboratory to search for evidence of small size configurations and their contributions to our fundamental understanding of nucleons.

Hyper-Kamiokande project

Abstract:Hyper-Kamiokande project consists with 3 components; Hyper-Kamiokande detector, J-APRC neutrino beam upgrade, and the near detector system. Hyper-Kamiokande detector is the 3rd generation of extremely successful water Cherenkov neutrino detectors at the Kamioka Observatory, Japan (Nobel Prize in Physics, 2002 and 2015). It is a 261 kton water tank with roughly 8 times the fiducial volume of Super-Kamiokande which will help us to push all science to an unprecedented level, including beam-based neutrino physics, astrophysics, and beyond-the-Standard-Model discovery science. In this talk, I will mainly discuss the status of the Hyper-Kamiokande detector construction and R&D.
