Ivan Burbano Aldana (UCB) “Real-time Estimators for Scattering Observables: A full account of finite-volume errors for quantum simulation”
Abstract: Lattice QCD is the only known systematically improvable tool we have for the determination of non-perturbative QCD observables from first principles. However, in its standard incarnation, the study of scattering observables beyond the three-particle energy threshold has been hindered by a number of challenges due to its Euclidean nature. In this talk I will give motivation for the lattice … Read More
Erwin Tanin (Stanford) “Cosmology of dark forces: strong limits and 𝜈 effects”
n the first three quarters of the talk, I will explain how cosmology sets the strongest constraints yet on long-range dark matter self-interactions at length scales shorter than 100 kpc. In the last quarter, hopefully, I will briefly discuss the early-universe dynamics of an ultralight scalar dark matter coupled to neutrinos, focusing on the dissipative backreaction of the neutrinos on … Read More
Zahra Tabrizi (Pittsburgh U.) “EFT at Neutrino Experiments”
Abstract: We will discuss how to systematically study physics beyond the standard model (BSM) in neutrino experiments within the Standard Model Effective Field Theory (SMEFT) framework. In this way, the analysis of the data can capture large classes of models, where the new degrees of freedom have masses well above the relevant energy of the experiments. Moreover, it allows us to … Read More
Bruno Scheihing (UCSB) “Probing deconfined QCD matter with heavy quarks”
The dynamics of heavy particles propagating through a thermal environment has been a topic of interest in theoretical physics (at least) since the times of Einstein’s theory of Brownian motion. The simultaneous production of heavy quarks and quark-gluon plasma in heavy-ion collisions provides an ideal configuration in which to test and extend our understanding of this process in relativistic settings … Read More
Giuseppe Lucente (SLAC) “$\nu p$-process in neutrino-driven outflows: Imprints of general relativistic effects”
Abstract: The origin of several proton-rich isotopes in the solar system, most notably $^{92,94}$Mo and $^{96,98}$Ru, remains a long-standing problem in nucleosynthesis. A promising explanation is the $\nu p$-process, which operates in proton-rich, neutrino-driven outflows from the surface of a protoneutron star formed in a core-collapse supernova (CCSN). Years of detailed studies, however, failed to reproduce the observed abundances of … Read More
Mia West (University of Florida) “Chiral Symmetry Breaking, Gravitational Waves and the Origin of the Dark Eta Prime Mass in Confining Dark Sectors.”
Abstract: Dark confining sectors are phenomenologically rich: for instance a confining phase transition can be used to trigger baryogenesis, and some heavy axion models identify the dark \eta′ particle as an axion candidate. By modelling the dark confining phase transition with spontaneous symmetry breaking of chiral symmetry, previous studies have found that a Gravitational Wave (GW) signal could be visible … Read More
