Title: B-flavor tagging at Belle II

Abstract

We report on new flavor tagging algorithms developed to determine the quark-flavor content of bottom (B) mesons at Belle II. The algorithms provide essential inputs for measurements of quark-flavor mixing and charge-parity violation. We validate and evaluate the performance of the algorithms using hadronic B decays with flavor-specific final states reconstructed in a data set corresponding to an integrated luminosity of 62.8fb^-1, collected at the Υ(4S) resonance with the Belle II detector at the SuperKEKB collider. We measure the total effective tagging efficiency to be ε_eff = (30.0 ± 1.2(stat) ± 0.4(syst))% for a category-based algorithm and ε_eff = (28.8 ± 1.2(stat) ± 0.4(syst))% for a deep learning-based algorithm.

A Study of Time-Dependent CP-Violating Asymmetries and Flavor Oscillations in Neutral B Decays at the Upsilon(4S)

Technical Report MacFarlane, David B

We present a measurement of time-dependent CP-violating asymmetries in neutral B meson decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample consists of 29.7 fb{sup -1} recorded at the {Upsilon}(4S) resonance and 3.9 fb{sup -1} off-resonance. One of the neutral B mesons, which are produced in pairs at the {Upsilon}(4S), is fully reconstructed in the CP decay modes J/{psi} K{sub S}{sup 0}, {psi}(2S) K{sub S}{sup 0}, {chi}{sub c1} K{sub S}{sup 0}, J/{psi} K*{sup 0} (K*{sup 0} {yields} K{sub S}{sup 0}{pi}{sup 0}) and J/{psi} K{sub L}{sup 0}, or inmore »« less

Search for B{sup +}{yields}{tau}{sup +}{nu} decays with hadronic B tags

We present a search for the decay B{sup +}{yields}{tau}{sup +}{nu} using 383x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the BABAR detector at the SLAC PEP-II B Factory. We select a sample of events with one completely reconstructed tag B in a hadronic decay mode (B{sup -}{yields}D{sup (*)0}X{sup -}), and examine the rest of the event to search for a B{sup +}{yields}{tau}{sup +}{nu} decay. We identify the {tau} lepton in the following modes: {tau}{sup +}{yields}e{sup +}{nu}{nu}, {tau}{sup +}{yields}{mu}{sup +}{nu}{nu}, {tau}{sup +}{yields}{pi}{sup +}{nu}, and {tau}{sup +}{yields}{pi}{sup +}{pi}{sup 0}{nu}.
