The XENON1T Electronic-Recoil Excess
/ Tunnell, Christopher (speaker) (Rice University, Houston (US))
Our XENON collaboration has been operating a series of ultra-radiopure experiments to probe tiny momentum transfers, which may arise from cosmogenic particles. Traditionally, we interpret our results in terms of WIMP dark matter, where our latest XENON1T experiment is the most sensitive such detector to date [...]

Search for $H \to \mu^+ \mu^–$ at ATLAS and CMS
/ Vartak, Adish Pradeep (speaker) (Univ. of California San Diego (US)) ; Artoni, Giacomo (speaker) (University of Oxford (GB))
The seminar presents searches for the Higgs boson decay to a pair of muons performed by the ATLAS and CMS Collaborations. The analyses are based on the full datasets collected at 13 TeV during Run 2 of the LHC, corresponding to 140 fb-1 per experiment. [...]

QUANTUM SENSORS of the DARK and EARLY UNIVERSE: Exploiting Quantum Entanglement in the Laboratory for Detection of Particles and Fields Beyond the Standard Model (BSM) and signals from Very Early Universe
/ Chattopadhyay, Swapan (speaker) (Distinguished Scientist, Fermilab, USA and President’s Professor of Research, Scholarship and Artistry Northern Illinois University, USA )
After an introduction of the extraordinary success of large particle accelerators, colliders and classical detectors of the late twentieth and early twenty-first centuries in developing the now widely accepted Standard Model (SM) of particle physics, I will introduce and expose the basic concepts and techniques of “quantum sensors”, illustrate “quantum entanglement” at work around us and its controlled exploitation in the laboratory to detect with high precision very weak signals of exotic particles and fields that may exist Beyond the Standard Model (BSM) and signals from the emerging “early” and “dark” universe.
Our immediate familiar natural world as well as our known universe, as it supposedly emerged
from the “Big Bang” 13.8 billion years ago, are "quantum-entangled" from the microscopic to the macroscopic scale, from the "inner" to the "outer" dimensions. This fundamental "quantum entanglement" can be harnessed to sense and probe extremely "weak" processes and signals in nature around us – signals left over from the very “early” and “dark” universe, allowing us to be ‘cosmic archaeologists’ [...]

The LHC as a photon collider with the ATLAS detector
/ Kepka, Oldrich (speaker) (Czech Academy of Sciences (CZ))
Abstract: Photon fusion is a rare and interesting process at proton and ion colliders, involving purely electroweak interactions and allowing precision tests of the gauge structure of the Standard Model. Experimentally it has a remarkably clean signature with little (if any) remnant activity from the interacting beam particles, although this signature is very difficult to identify in the harsh experimental conditions at the LHC. In this seminar, recent ATLAS photon fusion results are presented: the observation of photo-produced weak-boson pair-production, cross-section measurement of lepton pair production with proton tagging in the ATLAS Forward Proton Spectrometer, and studies of light-by-light scattering.

Investigating light nuclei production in heavy-ion collisions using flow measurements in ALICE
/ Caliva, Alberto (speaker) (GSI - Helmholtzzentrum fur Schwerionenforschung GmbH (DE))
The production mechanisms of light (anti)nuclei in ultrarelativistic heavy-ion collisions are still not understood and currently under intense debate in the scientific community. Light (anti)nuclei have binding energies that are typically much less than the temperature at which they are produced (T ≈ 156 MeV), and mysteriously survive under the extreme conditions of the hadron gas phase [...]

Quantum Computational Supremacy and Its Applications
/ Aaronson , Scott (speaker) (UT Austin, US)
Last fall, a team at Google announced the first-ever demonstration of "quantum computational supremacy"---that is, a clear quantum speedup over a classical computer for some task---using a 53-qubit programmable superconducting chip called Sycamore. Google's accomplishment drew on a decade of research in my field of quantum complexity theory. This talk will discuss questions like: what exactly was the (contrived) problem that Sycamore solved? How does one verify the outputs using a classical computer? And how confident are we that the problem is classically hard---especially in light of subsequent counterclaims by IBM and others? I'll end with a possible application that I've been developing for Google's experiment: namely, the generation of trusted public random bits, for use (for example) in cryptocurrencies.
