CLEO-c and CESR-c: A New Frontier in Weak and Strong Interactions

AIP Conf.Proc. 618 (2002) 427-437

Abstract:

We report on the physics potential of a proposed conversion of the CESR machine and the CLEO detector to a charm and QCD factory: CLEO-c and CESR-c that will make crucial contributions to flavor physics in this decade and offers our best hope for mastering non-perturbative QCD which is essential if we are to understand strongly coupled sectors in the new physics that lies beyond the Standard Model.

Abstract:

We present an improved measurement of b-meson lifetimes using fully reconstructed B-decays produced in pp虅 collisions at 鈭歴 = 1.8 TeV, using 114 pb-1 of data collected at the Collider Detector at Fermilab. We obtain 蟿(B+) = 1.636卤0.058(stat)卤0.025(syst) ps, 蟿(B0) = 1.497卤0.073(stat)卤0.032(syst) ps and for the lifetime ratio 蟿(B+)/蟿(叠0) = 1.093卤0.066(stat)卤0.028(syst).

Abstract:

We search for standard model single-top-quark production in the W-gluon fusion and W* channels using 106 pb-1 of data from pp虅 collisions at 鈭歴=1.8 TeV collected with the Collider Detector at Fermilab. We set an upper limit at 95% confidence level (C.L.) on the combined W-gluon fusion and W* single-top cross section of 14 pb, roughly six times larger than the standard model prediction. Separate 95% C.L. upper limits in the W-gluon fusion and W* channels are also determined and are found to be 13 and 18 pb, respectively.
