Christian Bauer (LBNL) "GENEVA: Combining perturbative calculations with parton showers"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

ABSTRACT: I will discuss the event generator GENEVA, which for the first time combines fixed order and resummed perturbative calculations with parton showering and hadronization. I will explain the basic physics concepts underlying GENEVA, and show how they can be …

Chris Fassnacht (UC Davis) "Cosmological parameters from strong gravitational lenses"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract: Recent measurements of the Hubble Constant (H_0) through distance ladder techniques have revealed a noticeable tension with the Planck H_0 value that was obtained under the assumption of the cosmological "standard model", i.e., a flat Lambda cold dark matter …

Nicholas Carlini (UCB) "Adversarial Machine Learning"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract: Many fundamental properties of neural networks are still not well understood. This talk studies two of these from an adversarial perspective. I begin with my main line of research and examine the apparently-fundamental susceptibility of neural networks to adversarial …

Masashi Hazumi (KEK) "LiteBIRD Satellite for Tests of Cosmic Inflation and Quantum Gravity"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract: Cosmological inflation is the leading hypothesis to resolve the problems in the Big Bang theory. It predicts that primordial gravitational waves were created during the inflationary era, which then imprinted large-scale curl patterns in the cosmic microwave background (CMB) …

Joshua Spitz (U. Michigan) " First Measurement of Monoenergetic Muon Neutrino Charged Current Interactions

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

ABSTRACT: This talk will present the first measurement of monoenergetic muon neutrino charged current interactions. The MiniBooNE experiment at Fermilab has been used to isolate and study 236 MeV muon neutrino events originating from charged kaon decay at rest. The …

Adam Becker (UCB) "An Incomplete Survey of Proposed Solutions to the Quantum Measurement Problem"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

ABSTRACT: The central puzzle that drives the field of quantum foundations is the measurement problem: what gives rise to the appearance of wave function collapse? While there is no single answer to this question that has wide acceptance, this is …

Laura Newburgh (Yale U.) "New Probes of Old Structure: Cosmology with 21cm Intensity Mapping and the Cosmic Microwave Background"

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

ABSTRACT: Current cosmological measurements have left us with deep questions about our Universe: What caused the expansion of the Universe at the earliest times? How did structure form? What is Dark Energy and does it evolve with time? New experiments …
