Fluctuations provide a powerful tool for elucidating the nature of strongly-interacting matter in the QCD phase diagram. In heavy-ion-collision systems, the net-particle number fluctuations are captured at the moment of chemical freeze-out. Studies of the chemical freeze-out via susceptibilities from Lattice QCD and the Hadron Resonance Gas model contribute to the characterization of the transition region of the QCD phase diagram.

Noble liquid time projection chambers are ubiquitously used to search for rare events such
as neutrinoless double beta decay or dark matter interactions. A detailed understanding of
light and charge transport in liquid xenon is of the utmost importance when modeling the
performance of these experiments.
In this talk I will present the design and physics reach of the proposed nEXO experiment,
Jets are collimated sprays of hadrons produced in high energy collider experiments, such as
Why is the universe dominated by matter, and not antimatter? Neutrinos, with their changing flavors and tiny masses, could provide an answer. If the neutrino is a Majorana particle, meaning that it is its own antiparticle, it would reveal the origin of the neutrino’s mass, demonstrate that lepton number is not a conserved symmetry of nature, and provide a path to leptogenesis in the early universe. To discover whether this is the case, we must search for neutrinoless double-beta decay, a theorized process that would occur in some nuclei.
Join us for the launch of the Yale IPCH Public Talks: a series dedicated to exploring global perspectives and critical developments that impact cultural heritage preservation. In this inaugural event, this distinguished expert panel will contextualize the highly anticipated John Randle Centre for Yoruba History and Culture within the economic, social, and cultural landscape of Lagos, the most populous city on the African continent.
Abstract: Intensity mapping of redshifted 21cm emission from neutral hydrogen holds great promise for learning about cosmology, as it provides an efficient way to map large volumes of the universe without the need to characterize individual luminous sources. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a cylinder telescope located in Western Canada that was custom-built for this purpose, and that has collected several hundred days’ worth of data since it reached full observational capacity in late 2018.
The MicroBooNE detector is a Liquid Argon Time Projection Chamber (LArTPC) located along the Booster Neutrino Beam (BNB) at Fermilab. One of its key physics goals is the measurement of neutrino-Argon interaction cross sections. Due to the detector’s fully active volume as well as its capability to offer a high-efficiency neutrino event selection, MicroBooNE is well suited produce the first ever triple-differential neutrino-Argon cross section.
The Wright Lab community is invited to a weekly meeting on Mondays at 9:30 a.m to hear about and discuss what is going on at the lab.
With an anticipated world population of over 9.5 billion by 2050, we face an unprecedented challenge to sustainably provide sufficient food, water, energy and healthcare. Convergence, the merging of previously distinct disciplines, has emerged as a powerful model with untold potential to drive a new cycle of innovation-based economic growth. Bringing together insights and discoveries from the life, engineering, computation and physical sciences holds the promise of accelerating discovery and the development of new technologies to meet the 21st century’s needs.
The physics of the time orientation of causation is more subtle than what it looks like superficially. For a long while it was reduced to a mere linguistic issue (a “cause” is just the term of a correlation that happens earlier, Hume). As emphasized by Russell, there is no time orientation in fundamental physics. But causation was later better understood as an essential notion in the context of an agent having choices, which after all is our own common context. This traces the time orientation of causation to the time orientation of agency.
