At CDF, we search for the associated production of a Higgs boson and a W boson, where the Higgs boson decays into a b + anti-b quark pair and the W boson decays into a lepton and the corresponding neutrino. Events are selected with a signature of a lepton, large missing transvers energy, and two or three jets. The events are selected by a variety of triggers, and those triggers are divided...

A search for dark matter particles and large extra dimensions in events with an energetic jet and an imbalance in transverse momentum is performed in a sample of pp collision data corresponding to an integrated luminosity of 5.0 fb-1collected at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The data are in good agreement with the expected contributions from standard model...

Optimizing the performance of the CMS Electromagnetic Electromagnetic Calorimeter is crucial for a successful search for Higgs in the diphoton decay channel. In this talk, we will review the work done over the past two years to optimize the ECAL performance with an emphasis on the ECAL calibration and monitoring techniques.

In this talk, we will present a brief overview of the CMS Tier3 site at Texas A&M Universty. It is largely unique in that we added resources to an already-existing cluster to create our site as opposed to creating a stand-alone system. We will comment on some of the particulars of our site, the advantages and disadvantages of this choice, as well as how it has performed. We will also discuss...

Several models of new physics, including split supersymmetry, predict the existence of a heavy particle, which is long-lived on timescales of the bunch spacing of the LHC. Such a particle would be observable using the Compact Muon Solenoid (CMS) at the Large Hadron Collider (LHC), and although produced at high momentum, it would travel slowly due to its large mass. We describe a search for...

The analysis to search for the Standard Model Higgs boson in high Pt lepton + 2 jets events is performed at the CDF experiment. To extract the information of signal like events from data, Dynamical Likelihood Method(DLM) is established. For the separation of signal against backgrounds, Support Vector Machine(SVM) is applied using the result of DLM and the final discriminant is formed with SVM...
