Search for Higgs, Leptoquarks, and Exotics at Tevatron
This paper reviews some of the most recent results from the CDF and DZERO
experiments on the searches for Standard Model and Non-Standard Model Higgs
bosons, and other new phenomena at the Tevatron. Both experiments examine data
from proton anti-proton collision at sqrt{s} = 1.96 TeV, of integrated
luminosity ~200$ pb**-1 (per experiment), to search for Higgs predicted in the
Standard Model and beyond Standard Model, supersymmetric particles in the Gauge
Mediated Symmetry Breaking scenario, leptoquarks, and excited electrons. No
signal was observed, and limits on the signatures and models are derived.Comment: Contribution to the proceedings of the XXXIX Recontres de Moriond on

Hot medium effects on J/psi production in p+Pb collisions at sqrt{s_{NN}}=5.02 TeV
Based on a kinetic description of J/psi dissociation and production in an
expanding quark-gluon plasma that is described by a 2+1 dimensional ideal
hydrodynamics, we have studied the hot medium effects on J/psi production in
p+Pb collisions at sqrt{s_{NN}}=5.02 TeV. Including also the cold nuclear
matter effects, we are able to reproduce recent experimental results on the
nuclear modification factor R_{pPb}(J/psi) measured by the ALICE Collaboration.
We have also made predictions for the R_{pPb} of J/psi and the double ratio
R_{pPb}^{pro}(psi')/R_{pPb}^{pro}(J/psi) of prompt quarkonia produced in the
most central 10% p+Pb collisions. We find that different from the cold nuclear
matter effects, the R_{pPb}(J/psi) is slightly smaller than that in the minimum
bias collisions, and the double ratio is significantly less than one at
backward rapidity.Comment: 8 pages, 6 figure
