Direct Measurement of A b in Z 0 Decays using Charged Kaon
We present a direct measurement of the parity-violating asymmetry A b in the Z 0 to bb coupling using a new technique to distinguish the b and b quarks using charged kaons from B decays. The Z 0 bosons are produced in e + e collisions at the SLC with longitudinally polarized electrons. bb events are selected using a secondary ver-tex mass tag and A b is determined from the left-right forward-ba...
متن کاملKLOE measurement of the charged kaon absolute semileptonic BR’s
This paper is devoted to the measurement of the fully inclusive of photon radiation absolute branching ratios of the semileptonic charged-kaon decays, K ± → π 0 e ± ν(γ) and K ± → π 0 µ ± ν(γ). The measurements have been done using a tag technique, via identification of the two-body decays K ± → µ ± ν and K ± → π ± π 0 , and using a sample of about 410 pb −1 collected during the 2001 and 2002 d...
متن کاملCharged kaon analysis within the CERES experiment
Strangeness production in heavy ion collisions has raised and continues to raise interest both in experimental and theorist communities [3], [4]. In this report the status of the analysis of charged kaons registered via three charged pions decay is presented. After the upgrade of the CERES (NA45) [1] experimental setup in 1998 with a radial Time Projection Chamber (TPC) [2], the accessible phys...
متن کاملRecent results on Direct CP Violation and charged kaon decays with the NA48/2 experiment
The CP violation played an important role in the understanding of the intimate nature of the weak interaction from the early times of particle physics. After more than three decades since the discover of CP violation in the neutral kaons by Christenson, Cronin, Fitch and Turlay [1] a new kind of CP violation, the so called Direct CP violation that happens directly in the decay, was definitively...
متن کاملDirect measurement of three-body interactions amongst charged colloids.
Three-body interactions amongst three charged colloidal particles are measured in a deionized aqueous solution. Two of the particles are confined to an optical line trap while the third one is approached by means of a focused laser beam. From the observed particle configurations we extract the three-body potential which is found to be attractive and roughly of the same magnitude and range as th...
