Quasi-model-independent search for new high p(T) physics at D0.

Searches for New Physics at the Tevatron

Recent results of searches for new phenomena using data collected in Run I by the CDF and D0 experiments are presented. D0 set limits for top squarks decaying into blν̃ significantly beyond the reach of previous analyses in this channel (mt̃>140 GeV at 95% C.L. for mν̃ =45 GeV). CDF exclude top squarks decaying into bτ for masses below 111 GeV. In addition, D0 have analyzed photon and electron pai...

Model-independent and quasi-model-independent search for new physics at CDF

A quasi-model-independent search for new electroweak scale physics

These proceedings describe Sleuth, a quasi-model-independent search strategy targeting new electroweak scale physics, and its application to 927 pb of CDF II data. Exclusive final states are analyzed for an excess of data beyond the Standard Model prediction at large summed scalar transverse momentum ( P pT ). This analysis of highP pT data represents one of the most encompassing searches so fa...

A Search for B + → K + νν with BABAR

The study of flavor-changing neutral current decays is of fundamental interest. They provide a sensitive window in which to search for possible new physics effects beyond the Standard Model of particle physics. Measurements of these processes at rates significantly above the Standard Model would point, unambiguously, to new physics. One such decay of interest is B+ → K+νν . Herein, we discuss t...

Search for D0−D0 Mixing

We report on a search for D0−D0 mixing made by a study of the ‘wrong-sign’ process D →K+π−. The data come from an integrated luminosity of ee collisions at √ s ≈ 10GeV consisting of 9.0 fb, recorded with the CLEO-II.V detector. We measure the time-integrated rate of the ‘wrong-sign’ process D → Kπ, relative to that of the Cabibbo-favored process D →K+π−, to be Rws = (0.34 ± 0.07 ± 0.06)%. We st...
