30. Highlights of Search for New Particles at the LHC

Sergei Chekanov (Argonne National Laboratory (US))

25/05/2022, 10:50

This presentation discusses searches for heavy particles by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC). The talk discusses a motivation for such searches and the experimental challenges to discover heavy particles in the mass range from 400 GeV to 8 TeV using jets, leptons and missing transverse energy. The presented experimental limits use the LHC Run 2 dataset...

36. Status and Prospect of Search for LLP

Christina Wenlu Wang (California Institute of Technology (US))

Many extensions of the standard model (SM) predict the existence of weakly-coupled particles that have a long lifetime. These long-lived particles (LLPs) often provide striking displaced signatures in detectors, thus escaping the conventional searches for prompt particles and remaining largely unexplored at the LHC. I will discuss the broad search program for LLPs enabled by the unique...

49. Tumblers: A Novel Collider Signature for Long-Lived Particles

Brooks Thomas (Lafayette College)

In this talk, we point out a novel signature of physics beyond the Standard Model which could potentially be observed both at the LHC and at future colliders. This signature, which emerges naturally within many proposed extensions of the Standard Model, results from the multiple displaced vertices associated with the successive decays of unstable, long-lived particles along the same decay...

9. Probing the Supersymmetric Grand Unified Theories at the Future Proton-Proton Colliders and Hyper-Kamiokande Experiment

Gauge coupling unification in the Supersymmetric Standard Models strongly implies the Grand Unified Theories (GUTs). With the grand desert hypothesis, we show that the supersymmetric GUTs can be probed at the future proton-proton (pp) colliders and Hyper-Kamiokande experiment. For the GUTs with the GUT scale $M_{GUT} \le 1.0\times 10^{16}$ GeV, we can probe the dimension-six proton decay via...
