It was the best of times, it was the worst of times. Just as the classic English novel lends its title well to the spirit of understanding symmetries in the standard model (SM), the opening words also concisely sum up the status of beyond standard model (BSM) physics searches through tests of the fundamental symmetric matrices over the past few decades. Despite the identical mathematical formalism that generates these matrices in the SM, empirically the level of observed mixing within these two are dramatically different.

Wright Lab will host two, identical 1-hour Environmental Health and Safety (EHS) Shop Orientations on Friday, January 26 at 11:30 a.m. and Tuesday, January 30 at 3:00 p.m. 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.

Quark-gluon plasma (QGP), a unique phase of matter governed by Quantum Chromodynamics (QCD), is believed to have existed shortly (a few microseconds) after the Big Bang. Jets, collimated particle sprays originating from the fragmentation of hard-scattered quarks or gluons, serve as valuable probes for studying QGP produced in relativistic heavy ion collisions. As jets experience modifications due to the surrounding medium, so-called jet quenching, concurrently, jets influence the medium.
This workshop, presented by Yale Physics’ Professor Reina Maruyama and Assistant Professor Laura Havener, will focus on how to prepare for the academic job market, including:
- how to find and apply for postdoc and faculty positions
- how to prepare your application package, including CV, research statement, teaching statement, etc.
- having a successful postdoctoral experience, and becoming an assistant professor
Host: Fernando Flor
This workshop is designed to introduce new users to the HPC resources available at Yale and to provide a comprehensive overview of the basic concepts needed to perform computing on the clusters:
accessing the clusters,
navigating a linux interface via bash commands, running interactive and batch jobs,
troubleshooting workflows, and more.
Building upon two decades of edge-finding archaeological research, the Yale Ancient Pharmacology Program continues to refine a transdisciplinary approach that seamlessly blends ethnography, materiality, and technology. Nucleating at the Yale Peabody Museum has allowed YAPP to work across its divisions and vast collections to push our knowledge of ancient organic materials through the fusion of ethnohistory, phytochemistry, and data science.
The ages of astronomical objects, while not directly measurable, are of use in constructing chronologies, and the key to understanding origins. The ages of cool field dwarfs, although important in a Galactic context, are especially challenging to obtain. I will present a route to the ages of such objects that is called “Gyrochronology,” one based on the measured rotation periods of such stars.
The Koba-Nielsen-Olesen (KNO) scaling hypothesis is an influential contribution to the analysis of event multiplicities in high-energy particle collisions, according to which the event-multiplicity distributions can be all collapsed onto a universal scaling curve. Recent phenomenological studies suggest that a similar scaling may hold within single jets, if we consider the jet multiplicity as a function of the jet transverse momentum.
It has been realized recently that Type Ia supernova are the most sensitive distance indicators in measuring the Hubble Constant. Our Yale group has been collaborating with the Carnegie Observatory Group (Mark Phillips, Wendy Friedman, et al) with our La Silla/QUEST Supernova Survey providing a substantial part of the supernovae for the most recent precision measurement of the Hubble Constant. Results of this measurement will be presented and and its significance discussed.
