The Experimental Particle Physics Group at New York University is thriving! Our primary focus is the ATLAS experiment at the Large Hadron Collider. We recently hired a new faculty member and a research associate, and now have several key roles in ATLAS. We are also key contributors to the APEX experiment, at Jefferson Lab; are active in the LHC upgrade and the MILAGRO experiment; and were involved in the MECO experiment before its termination. Please have a look at our group.
Nobel DreamsThe Nobel Prize in Physics will be announced on Tuesday, October 8. In the event that the prize is related to the discovery of the Higgs boson, we will be holding a small celebration on the 5th floor of Meyer Hall (4 Washington Pl).
Observation of a new Higgs-like particle at a mass of ~126 GeV
On July 4, 2012, CERN held a joint ATLAS+CMS seminar where each experiment presented results indicating the observation of a new particle consistent with the Standard Model Higgs boson with a measured mass of ~125-127 GeV. The excess of Higgs-like events was observed in several possible decay channels, each of which required a separate analysis, and the NYU ATLAS group was (and is) heavily involved in two of these analyses: Higgs-to-four-leptons and Higgs-to-two-photons. Additionally, all of the separate analyses needed to be combined for the final ATLAS result, published in Physics Letters B. In the ATLAS Collaboration, this Higgs combination task fell to a small group of experts, one of whom was our own Kyle Cranmer, Editor of the combination paper.
This is a major milestone not just in particle physics but in the history of science, and the NYU group is proud to have played a part in the discovery. The observation of a new boson is just the first step, however. Further analyses are underway to examine the properties of this particle to determine whether it is indeed the Standard Model Higgs or something different (and there are intriguing hints that this is the case).
- May 17, 2013: George Lewis graduates with his Ph.D. based on his thesis entitled “Measurements and Searches for New Physics Using Top Quarks at the LHC”.
- March 14, 2013: Our group played a key role in new results from ATLAS that indicate that the new particle has no spin, strongly indicating it is indeed a Higgs boson. In addition, several measurements of the particle's production and decay properties have been made to test if this is the Higgs boson predicted by the Standard Model. [results, press release]
