Hi! I'm Joey Reichert.
I'm a staff scientist at Rutgers University, where I work as an experimental particle physicist on the CMS Experiment.

I'm a staff scientist at Rutgers University, where I work as an experimental particle physicist on the CMS Experiment.
Learn about me and my researchMy current research focuses on searches for new physics using the CMS Experiment at the CERN Large Hadron Collider (LHC). This includes scenarios with new long-lived particles which could be discovered by identifying their decay points as displaced vertices, as well as other searches for exotic forms of new and unconventional physics signatures such as soft unclustered energy patterns ("SUEPs"). I am a member of the graduate faculty of the Rutgers University Physics and Astronomy Department, and am actively taking on undergrad and graduate students to work on these interesting research problems. I am also responsible for the Rutgers "HEX farm", which is a Tier-3 computing facility.
As a Karl Berkelman postdoctoral fellow at Cornell University, I was actively involved in studying upgrades to the CMS pixel detector via test beam studies of pixel sensor prototypes at the Fermilab Test Beam Facility and in building a quality control center for the CMS Phase-2 pixel detector upgrades. As a graduate student at the University of Pennsylvania, I worked on the ATLAS Experiment, where I focused on searches for electroweak supersymmetry, particularly in compressed scenarios. I also spent considerable time developing and refining the electron identification algorithm used by the entire experiment (both at trigger-level and offline), measuring the electron identification efficiency, and performing studies of prototype readout chips for the future ATLAS ITk Strip detector via irradiation studies at BNL and the CERN Proton Synchrotron. More detail can be found in my PhD thesis.

As a member of the ATLAS and CMS collaborations, I have been a co-author of over 750 publications. A very brief selection of publications which I had significant involvement on is below.
First-of-its kind search for SUEPs produced in association with a W boson, focusing on Higgs-portal dark sector scenarios.
Review paper covering all searches for dark sectors at CMS, including many new interpretations and summary plots.
CMS search for long-lived particles in events with large missing transverse momentum. To target long-lived particles in compressed scenarios that could previously evade detection due to their soft visible decay products, events are selected with at least one displaced vertex and background is suppressed using an interaction network. This search improves upon previous limits for some models of long-lived particles by up to a factor of 50.
CMS search for long-lived particles in events with large hadronic activity, using the full Run 2 dataset. This search improved upon previous limits for long-lived particles by a factor of four or more, and provides the strongest limits to date on these models for lifetimes between 100 μm and 15 mm.
ATLAS search for compressed electroweak SUSY, based on 2015-2016 data. This was the first search for the well-motivated scenario with direct production of compressed Higgsinos since the LEP experiments in the early 2000s.
ATLAS paper describing the electron reconstruction, identification, and isolation algorithms and their corresponding efficiencies, based on 2015-2016 data.
ATLAS search for electroweak SUSY in dilepton and trilepton final states, based on 2015-2016 data.
