Spring 2024 EHS Orientation for Wright Lab Shops

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.

NPA Seminar: Yeonju Go, BNL, "Jets and medium response in relativistic heavy ion collisions: Probing quark-gluon plasma"

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.

YPPDO Workshop: Preparing for Faculty Positions with Laura Havener and Reina Maruyama

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

Introduction to HPC

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,
managing files,
troubleshooting workflows, and more.

From Cross Campus to West Campus to Science Hill: The Yale Ancient Pharmacology Program

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.

Astronomy & Astrophysics Colloquium: Sydney Barnes - Gyrochronology: a route to the ages of cool field stars

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.

NPA Seminar: Zoltan Varga, Wigner Research Centre for Physics, "Studying the multiplicity dependence of jet properties and the role of the underlying event in pp collisions"

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.

NPA Seminar: Charles Baltay, Yale, "Precision Measurement of the Hubble Constant Using Type Ia Supernovae"

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.

WIDG Seminar: Arianna García Caffaro, Yale, "Probing the Higgs CP Structure and Quantifying QCD Systematics in Jet Substructure Techniques"

Since the Higgs boson’s discovery in 2012, the High Energy Physics community has centered its efforts on thoroughly studying this particle’s properties. As a step towards that goal, the ATLAS Collaboration has undertaken a study of the CP nature of the Higgs Yukawa coupling to the tau lepton. A Run 2 analysis has measured the CP mixing angle to be 9 ± 16°, excluding the pure CP-odd Higgs hypothesis at 3.4σ. The next iteration of this analysis with partial Run 3 data is underway.

NPA Seminar: Jennet Dickinson, Fermilab, "Boosted Higgs boson production via vector boson fusion with the CMS experiment"

A first search is conducted for boosted Higgs boson production via vector boson fusion in the H(bb) decay channel at the LHC proton-proton collider. The result is based on the full 13 TeV dataset collected by the CMS detector in 2016, 2017, and 2018, corresponding to an integrated luminosity of 138 fb^{-1}. Jet kinematics are used to define independent regions targeting vector boson fusion (VBF) and gluon fusion (ggF) production of Higgs bosons with p_T>450 GeV.
