摘要:

We report the observation ofCPviolation in theB0meson system. Using a novel technique for time-dependent measurements, we measure a non-zero value for theCP-violating amplitudesin&hthinsp;2&bgr;at the 4.1 &sgr; level. We also report on precision measurements of theB+andB0lifetimes and theB0B¯0mixing frequency&Dgr;mdobtained with the same technique, and on a first measurement of the time-dependentCP-violating amplitude inB0→&pgr;+&pgr;−decays. ©2002 American Institute of Physics.

摘要:

An analysis of the CKM matrix parameters within theRfit approach is presented using updated input values with special emphasis on the recentsin&hthinsp;2&bgr;measurements from BABAR and Belle. The QCD Factorisation Approach describingB→&pgr;&pgr;,K&pgr;decays has been implemented in the software package CKMfitter. Fits using branching ratios and CP asymmetries are discussed. ©2002 American Institute of Physics.

摘要:

I present a review of the results obtained during 10 years of activity inb-physics at LEP. Special emphasis will be put on measurements that attained precisions not even envisaged at the beginning of the LEP program(Vuband&Dgr;ms).Finally the impact of these measurements on the CKM parameters determination will be presented. ©2002 American Institute of Physics.

摘要:

Results onB-lifetimes,BdoandBsomixing, and B decay charm counting studies from the SLD experiment at the Stanford Linear Accelerator Center are presented. These results which exploit the small stable beam spots and high precision detector and the polarized electron beam are among the most precise measurements to date. ©2002 American Institute of Physics.

摘要:

Run II at the Tevatron has begun. The DO&slash; detector is expected to collect nearly 2 fb−1of data ats=2.0 TeVfor Run II in approximately 2 years with a design instantaneous luminosity of2×1032 cm−2&hthinsp;s−1.This large data set will allow precision measurements in a number of importantBphysics areas and new measurements inBdecays. This paper describes the prospects for several importantBphysics measurements, includingsin(2&bgr;)usingB→J/&psgr;Ks0decays,&Dgr;msusingBsmixing, the&Lgr;blifetime and rareBdecays. ©2002 American Institute of Physics.

摘要:

The measurement of the direct CP violation in the neutral kaon system has been performed by the NA48 collaboration at the CERN SPS. The result ofRe(&Vegr;′/&Vegr;)from the 98 and 99 data is(15.0±2.7)×10−4,which confirms the existence of a directCPviolation. ©2002 American Institute of Physics.

摘要:

An update of the current status of direct-CPviolation measurement,&Vegr;′/&Vegr;,from Fermilab KTeV experiment is reviewed here. Such long-sought effect in the two-pion system of neutral kaon decays has been observed and confirmed in the KTeV data. A recent preliminary result from the combined KTeV 1996–1997 run data findsRe(&Vegr;′/&Vegr;)=(20.7±2.7)×10−4.The new world average on this important measurement is thenRe(&Vegr;′/&Vegr;)=(17.2±1.8)×10−4with a confidence level of 13&percent; which clearly establishing the existence of “direct”CP-violation. ©2002 American Institute of Physics.
