Rutgers CDF Physics

Welcome to the Rutgers University Experimental High Energy Physics CDF Research page. CDF stands for the Collider Detector at Fermilab. CDF is an experiment at Fermilab, which is currently home to the world's most powerful particle accelerator called the Tevatron. The Tevatron accelerates protons and antiprotons close to the speed of light, and then makes them collide head-on inside the CDF detector. The CDF detector is used to study the products of such collisions. By doing this we try to reconstruct what happened in the collision and ultimately try to figure out how matter is put together and what forces nature uses to create the world around us!

Rutgers CDF Physics:

Exclusion region in pseudoscalar Higgs mass vs. tan(beta) from the h->tau tau analysis (Note that theoretically interesting regions below tan(beta) ~40 are becoming accessible to this analysis) Reference

CDF m0 - m1/2 mSUGRA limits derived from the Rutgers trilepton analysis. These are the first limits on chargino mass, shown on the right hand scale, from a hadron collider Reference

The measured W production charge asymmetry and predictions from (a) NLO CTEQ6.1 and (b) NNLO MRST 2006, with their associated PDF uncertainties Reference

Measurement of the fraction of t-tbar production via gluon-gluon fusion, Gf. In the data, we find fitf=0.073, which yields Gf=0.07-0.07+0.15 and Gf < 0.38 at the 95% C.L. Reference
