个人简介
I am interested in the High Energy physics. Specifically the interactions of the fundamental constituents of matter (quarks, leptons) and the forces that act on them. Non-experts, scroll down to see a link to a talk I gave at a local high school on particle physics.
The experiments in this field can be quite large, thousands of people collaborate on building and running a single experiment.
I am currently working at the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN
as well as on the CDF collider experiment at Fermilab (Fermi National Accelerator Laboratory).
Selected Papers:
CMS: Hadron Collider Physics at the LHC,
The Higgs discovery was announced on July 4, 2012. We lead one of the diphoton analyses, the Vector-Boson Fusion. In this mode, the proton proton collision produces Higgs particles by emitting W+W- bosons that interact to produce a Higgs. In the Standard Model, the rates for VBF are lower than the rates for general (glue-glue) production of the Higgs.
However, VBF opens a window on the electroweak symmetry breaking (why the Higgs was postulated in the first place, decades ago).
Our VBF result, submitted to JHEP, is here .
The 3jet resonance search we invented at CDF (see below) was also done at CMS. The large rates at the LHC mean that jet thresholds have to be set high, and therefore we could not search for the top excess we saw at CDF
(UPDATE: this is being addressed with special triggers in the 2012 run!)
The first CMS result came out with 2010 data in PRL (Physical Review Letters).
The result with 2011 data is being prepared for publication now, the public results are here .
A sophisticated multilepton search for new physics we did here at Rutgers with a large group has been accepted by JHEP . This analysis does not make any model-dependent selections, so is sensitive to most models of new physics that have leptons (Supersymmetry, 4th generation quarks, etc).
CDF: Hadron Collider Physics at the Tevatron,
We invented an entirely new technique to look for multi-jet resonances. With this technique we were able to see top quarks decay to 3 jets, without any additional kinematic requirements (like b-jets, W-resonance, leptons).
In other words, if you didn't already know that there was supposed to be a resonance at 175 GeV/c^2, this would have been one way to find it.
The paper was published in PRL .
Note that there was an excess of top quarks in this analysis. We did additional studies with more data. We looked for the signal of the W-boson within the top and found that the excess was indeed due to top quarks, and not some other 3jet resonance at similar mass.
Extra Plots for the multijet top excess.
On CDF we have performed one of the most sensitive searches for the MSSM Higgs Boson, published in Physical Review Letters in 2006.
We searched for Higgs decaying to tau leptons , and in the process greatly improved the status of tau physics at CDF.
Our work was highlighted in talks by Pier Oddone, director of Fermilab, as one of the most promising analyses being performed at the Tevatron.
We have a HREF="http://www-cdf.fnal.gov/physics/exotic/r2a/20050519.mssm_htt/index.htm"> website for this analysis, which includes our limit plots (one of which is also shown in the 2006 Particle Data Book) and plots showing expected sensitivity with higher luminosity.
We updated this result in 2009 in this PRL ,
