Search for Randall-Sundrum Gravitons in the Diphoton Channel at CDF
ثبت نشده
چکیده
We report on a search for new particles in the diphoton channel using a data sample of 5.4 fb−1 of pp̄ collisions at a center-of-mass energy of 1.96 TeV collected using the CDF II detector at the Fermilab Tevatron. The invariant mass spectrum of the data agrees well with the standard model expectation. We set upper limits on the cross section times branching ratio for the Randall-Sundrum graviton, as a function of diphoton mass. We subsequently derive lower limits on the graviton mass of 459 GeV/c2 and 963 GeV/c2, at the 95% confidence level, for coupling parameters (k/MPl) of 0.01 and 0.1 respectively.

متن کاملSearch for New Dielectron Resonances and Randall-Sundrum Gravitons at the Collider Detector at Fermilab
A search for new dielectron mass resonances using data recorded by the CDF II detector and corresponding to an integrated luminosity of 5.7 fb−1 is presented. No significant excess over the expected standard model prediction is observed. In this dataset, an event with the highest dielectron mass ever observed (960 GeV/c) was recorded. The results are interpreted in the Randall-Sundrum (RS) mode...
متن کاملSearch for New Physics in Dilepton and Diphoton Final States at CDF
The CDF detector has accumulated a large data sample of p p collisions at s =1.96 TeV at the Fermilab Tevatron. In this report we present the results of searches for physics beyond the Standard Model using final states of 2 leptons or 2 photons using 190 pb −1 to 448 pb −1 of data. No deviation from the predictions of Standard Model was observed. The non-observation was used to derive cross sec...
