Software and Physics Simulation at Belle II

The Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, will start physics data taking in 2018. It is planned to accumulate an e+ e- collision data set of 50 /ab, about 50 times larger than that of the earlier Belle experiment. The software library for the new detector will use GEANT4 for Monte Carlo simulation and is an entirely new software and reconstruction system based on modern computing tools. Examples of physics simulation including beam background overlays will be described.

A Review of Charm Semileptonic Decays

Several high energy experiments have been actively pursuing the analyses of semileptonic decays of charm mesons, resulting in numerous new results and publications. In this report, we summarize the recent efforts on the topics of pseudoscalar and vector charm semileptonic decays, especially in the area of branching fractions and form factor measurements.

Recent Results from CLEO

We report the initial results from CLEO-c based on the 55.8/pb data obtained at the psi(3770) resonance last year. We give a concise summary of the various CLEO-c analyses on leptonic and semileptonic decays of neutral and charged D mesons. The data used for this report is the first part of the psi(3770) data sets to be collected during next several years using the Cornell Electron Storage Ring. Most of the results shown here have already better or the same level of precision compared to the 2004 world averages compiled by the Particle Data Group.

Recent Results on CP Lifetime Differences of Neutral D Mesons

The mixing parameter y_cp for the neutral D system can be obtained by comparing the lifetimes of CP eigenstate decays of the D mesons. Recent results on the lifetime differences from the Belle, CLEO, FOCUS(E831) experiments are summarized in this article. The neutral D decay modes analyzed by the experiments are: The D0->Kpi mode with the assumption that it is an equal mixture of CP even and odd eigenstates, and the CP even modes D0->KK and D0->pipi.

Review of Charm Semileptonic Decays and QCD

In this paper, we review recent progress in the field of semileptonic decays of charm mesons, including topics on the relative branching ratio and the form factors. The comparison between the experimental form factor measurements and the Lattice QCD calculations is emphasized.

New Results from the FOCUS/E831 Experiment

The E831/FOCUS experiment at Fermilab is a photoproduction experiment which generated high quality charm particles. During its run, we obtained a large data set, including more than 1 million charm mesons in the Kpi/K2pi/K3pi mode decays. The current analysis efforts by the collaboration members are quite active and diverse. I will summarize the recent papers published by the FOCUS group on topics of semileptonic decays of charm mesons.
