NPA Seminar, Isaac Mooney, Wayne State University, “Jet substructure measurements in proton-proton and proton-gold collisions at RHIC”

Measurements of the substructure of high-momentum jets produced in proton-proton (pp) collisions give insight into fundamental aspects of QCD, from the production of highly virtual partons, to their subsequent radiation and hadronization. Additionally, once the evolution of jets in vacuum is calibrated, it is possible to study potential modification to jet substructure due to interaction with the cold nuclear medium present in proton-gold (pAu) collisions.

NPA Seminar, Ben Kimelman, UC Davis, "Phase Transitions and Where to Find Them: Probing the QCD Phase Diagram with Heavy-Ion Collisions"

Abstract: Relativistic heavy-ion collisions are a unique tool that allow us to probe QCD and its fundamental interactions; of particular interest is the phase transition between a hadron gas and a quark-gluon plasma (QGP). Characterizing this phase transition and mapping out the QCD phase diagram have been some of the primary goals of relativistic heavy-ion collisions over the past two decades. This talk will cover the background of the QGP and discuss a selection of the important observations over the past 22 years of RHIC operations relating to the QCD phase diagram.

Dissertation Defense: Benjamin Foust, Yale University, “Precise Measurement of the U-235 Antineutrino Energy Spectrum”

Neutrino experimentation is an important pathway to physics beyond the standard model, raising questions on how neutrinos obtain their vanishingly small but non-zero mass, what that mass is, and if they are their own antiparticle. Antineutrinos, as an abundant product of nuclear decay chains, are also important to advancing our understanding of nuclear physics and verifying nuclear databases.

Introduction to the Advanced Prototyping Center: Designing for rapid prototyping

In this workshop we will cover the equipment available at the Wright Lab Advanced Prototyping Center and how to get started designing parts. Basics of CNC laser and abrasive water jet cutting will be included, as well as an introduction to 3D printing. No prior experience is required, but having an idea for a project that you may want to get started on would be great. We will start off with a classroom presentation and then have a quick tour of the facilities.

NPA Seminar, Simone Mazza, UCSC, "4D tracking technologies and R&D"

Precision Timing information at the level of 10-30ps is a game changer for detectors at future collider experiments. For example, the ability to assign a timestamp with 30ps precision to particle tracks will mitigate the impact of pileup at the High-Luminosity LHC (HL-LHC). With a time spread of the beam spot of approximately 180ps, a track time resolution of 30ps allows for a factor of 6 reduction in pileup. HL-LHC will only be the first in HEP experiments to exploit the concept of 4D tracking using time as one of the parameters.
