Martin Savage (University of Washington) “Quantum Simulations for HEP and NP”

April 29 @ 4:00 pm - 5:00 pm
Zoom Talk, 50A-5132
Berkeley, ca 94720
+ Google Map

Abstract: Theoretical predictions of the properties and dynamics of quantum many-body systems of importance to  High-energy and nuclear physics research are anticipated to require, in many instances, beyond classical computational resources.  Such systems may be amenable to quantum simulations in the future, and the very first steps are now being taken towards these objectives. I will discuss the potential and status of this newly emerging area, with a focus on field theories. Slides http://physics.lbl.gov/rpm/index.php/events/ If you are looking to confirm…

Xiaosheng Huang (USF) “Strong Gravitational Lenses Discovered in the DESI Legacy Imaging Surveys”

May 6 @ 4:00 pm - 5:00 pm
Zoom Talk, 50A-5132
Berkeley, ca 94720
+ Google Map

ABSTRACT:We have discovered over 1500 new strong lensing candidates in the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys using residual neural networks.  The photometric redshifts of the candidate lenses are broadly distributed between 0.1 and 1.  Follow-up observations are underway.  Our Hubble Space Telescope SNAP program has confirmed all 47 of the candidates observed so far and our DESI Secondary Targets program for Year 1 will likely observe ∼400 candidate systems.  This sample will enable unprecedented tests of the…

Valerie Domcke (CERN) “Cosmology with Axion-Like Particles”

May 25 @ 12:30 pm - 1:30 pm
Zoom Talk, 50A-5132
Berkeley, ca 94720
+ Google Map

ABSTRACT: Axion-like particles may play a key role in early universe cosmology. They are naturally equipped with the right properties to explain cosmic inflation, can dynamically explain the smallness of the electroweak scale, may be involved in the generation of the matter antimatter asymmetry and are promising dark matter candidates. In this talk I discuss a generic but previously overlooked particle particle production mechanism, resulting in the dual production of gauge fields and fermions induced by axion-like particles. I will…

Mike Williams (MIT)   Searching for physics beyond the Standard Model at the LHCb experiment

May 27 @ 4:00 pm - 5:00 pm
Zoom Talk, 50A-5132
Berkeley, ca 94720
+ Google Map

Abstract:  The LHCb experiment at the Large Hadron Collider (LHC) at CERN has been the world's premier laboratory for studying processes in which the quark types (or flavors) change since 2011. Such processes are highly sensitive to quantum-mechanical contributions from as-yet-unknown particles, e.g. supersymmetric particles, even those that are too massive to produce at the LHC. I will discuss the status of these searches, including some intriguing anomalies. I will also present searches for the proposed dark matter analogs of…

Pedro Ochoa-Ricoux (UCI) “JUNO: a 20 kton Multi-Purpose Observatory for Neutrino Physics and Astrophysics”

June 24 @ 4:00 pm - 5:00 pm

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”

July 22 @ 4:00 pm - 5:00 pm
Zoom Talk, 50A-5132
Berkeley, ca 94720
+ Google Map

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,…
