We present results of a signature-based search for new physics using a dijet plus missing transverse energy (Missing E(t)) data sample collected in 2 fb-1 of p anti-p collisions at s**(1/2) = 1.96 TeV with the CDF II detector at the Fermilab Tevatron. We observe no significant event excess with respect to the standard model prediction and extract a 95% C.L. upper limit on the cross section times acceptance for a potential contribution from a non-standard model process. Based on this limit the mass of a potential first or second generation scalar leptoquark is constrained to be above 187 GeV/c2.

Abstract
We present results of a signature-based search for new physics using a dijet plus missing transverse energy (Missing E(t)) data sample collected in 2 fb-1 of p anti-p collisions at s**(1/2) = 1.96 TeV with the CDF II detector at the Fermilab Tevatron. We observe no significant event excess with respect to the standard model prediction and extract a 95% C.L. upper limit on the cross section times acceptance for a potential contribution from a non-standard model process. Based on this limit the mass of a potential first or second generation scalar leptoquark is constrained to be above 187 GeV/c2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
