Abstract: The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino detector under construction in China. With a 20 kton neutrino target, and an energy resolution of 3% at 1 MeV, it will be the largest and most precise liquid scintillator detector ever constructed. By studying the disappearance of antineutrinos emitted from 8 nuclear reactors at a strategic baseline of about 53~km, JUNO will determine the neutrino mass ordering to ~3σ significance within 6 years of running and will measure…

Anna Porredon (Ohio State University) “Dark Energy Survey Year 3 Results from Galaxy Clustering and Weak Lensing”
ABSTRACT: The cosmological information extracted from photometric surveys is more robust when multiple probes of the large-scale structure of the universe are used. Two of the most sensitive probes are galaxy clustering and weak lensing. I will present cosmological results from the Dark Energy Survey first three years of observations combining those two probes, using an optimized lens sample of 11 million galaxies for the clustering measurements. The shear catalog used for weak lensing contains more than 100 million galaxies,…

Anya Butter (Heidelberg University) “Big Data Techniques for Precision Simulations and Optimal Observables”
ABSTRACT: Over the next years, measurements at the LHC and the HL-LHC will provide us with a wealth of data. The best hope of answering fundamental questions like the nature of dark matter, is to adopt big data techniques in simulations and analyses to extract all relevant information. On the theory side, LHC physics crucially relies on our ability to simulate events efficiently from first principles. In the coming LHC runs, these simulations will face unprecedented precision requirements to match…

ABSTRACT: A summary of the latest results on the evidence of the four-top-quark production using proton-proton collision data at a centre of-mass energy of 13 TeV collected by the ATLAS detector at the Large Hadron Collider with an integrated luminosity of 139 fb−1. Events are selected if they contain a same-sign lepton (electron or a muon) pair or at least three leptons (2lSS/3l) or a single lepton or an opposite-sign lepton pair (1l/2lOS). A multivariate technique is used to discriminate…

Kendall Mahn (Michigan State University) “Results from T2K and the current landscape of neutrino oscillation”
Abstract: Neutrinos are a tiny subatomic particle with surprising properties under active study. In particular, neutrinos oscillate, that is, they convert from one type of neutrino to another, is a surprising phenomenon under active study. The origin of neutrino mass is important for astrophysics, cosmology and particle physics, and many open questions surrounding neutrino oscillation exist. The Tokai-to-Kamioka (T2K) neutrino oscillation experiment sends a beam of muon flavor neutrinos or antineutrinos 295km across Japan. This seminar will discuss the state…

ABSTRACT: I will review the Quantum Computing efforts in the Physics division, with the goal of allowing to calculate important properties of the Standard Model non-perturbatively and ultimately to simulate scattering at colliders from first principles. I will present several results, both on physics simulations and on noise mitigation, which is crucial to obtain results on near-term devices. http://physics.lbl.gov/rpm/index.php/events/ If you are looking to confirm if there is an event, due to room reservation, please go to RPM website for…

Abstract: There is an increasingly growing interest in Muon Collider in High Energy Physics community and Snowmass 2021. Considerable progresses have been made under the US Muon Accelerator Program (MAP) to target technical challenges associated with Muon Collider. The US MAP was recommended for termination by P5 in 2014, and all relavent R&D efforts and international MICE commitment officially ended in 2018. I will give an overview of the US MAP efforts on Muon Collider, technical challenges and progresses, in…
