NPA Seminar, Rene Bellwied, University of Houston, “From the Initial to the Final State - Quantum Entanglement in Relativistic Particle Collisions”

Collective quantum effects should play a significant role in the formation of hadrons from a deconfined and chirally symmetric state of matter. Yet most of our models ignore these effects or treat them as corrections after the dynamic calculation (e.g. color reconnection effects in PYTHIA). I will try to show that there is a direct connection between the entanglement entropy in the initial state and the thermodynamic entropy in the final state at least for elementary collisions where not too many decoherence effects are expected.

NPA Seminar, Yoshitaka Hatta, Brookhaven National Laboratory, “Azimuthal Angular Asymmetry of Soft Gluons in Jet Production”

We investigate the impact of soft gluon resummation on the azimuthal angle correlation between the total and relative momenta of two energetic final state particles (jets). We show that the initial and final state radiations induce sizable cos(ϕ) and cos(2ϕ) asymmetries in single jet and dijet events, respectively.

EHS Orientation for Wright Lab Shop Users - Spring 2022

Wright Lab will host 1-hour Environmental Health and Safety (EHS) Shop Orientations. The EHS shop orientation is offered each semester and is required to be taken once by anyone who would like to gain access and make use of the research and teaching shops at Wright Lab.

NPA Seminar, Alex Fieguth, Stanford University, “Probing Fundamental Physics With Levitated Force Sensors”

Microspheres have been the first objects optically levitated by Arthur Ashkin in the 1970s. While the technology itself was successfully used to trap atoms to explore new physics, the actual utilization of microspheres and other macroscopic objects as a useful tool for physics has emerged in the recent years. The unique properties of those levitated objects allows to deploy them as sensors with unmatched properties and advantages.

Connecting Past to Present: Building a Cultural Heritage Center in Lagos, Nigeria

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.

WIDG Seminar, Glenn Richardson, Yale, “Charge Reconstruction and Simulation in the nEXO Experiment”

Abstract: nEXO is a proposed tonne scale liquid xenon time projection chamber which plans to search for the neutrinoless double beta decay (0vbb) of Xe-136. 0vbb is a hypothetical nuclear process in which two neutrons decay into two protons and two electrons, with the notable absence of any neutrinos. Discovery of this hypothetical phenomena would help answer several questions concerning the mass of the neutrino, such as their Majorana nature. nEXO’s proposed detector design would allow it to search for this interaction with a half-life sensitivity greater than 10^{28} yrs.
