Abstract

A sample of {tau}{sup {+-}} {yields} K*{sup {+-}} decays with K*{sup {+-}} {yields} K{sub S}{sup 0}{pi}{sup {+-}} and K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -}, using 123.4 fb{sup -1} of data collected by the BaBar detector at the Stanford Linear Accelerator Center, is used to search for a direct CP violation effect in the charged Higgs sector. No evidence of CP violation is found and the imaginary part of the charged Higgs coupling, {l_brace}Im{r_brace}({Lambda}), in the Multi-Higgs-Doublet-Model is found to be at -0.284 < {l_brace}Im{r_brace}({Lambda}) < 0.200 at 90% Confidence Level. In addition the installation of the kk2f Monte Carlo generator into the BaBar software framework is described.

Technical Report Wah, Yau W.

This report discusses the progress on the measurement of the direct CP violation parameter {var epsilon}{prime}/{var epsilon} and the rare KL decay. The progress has been as follows: (A) results from the complete E731 data set which was collected in the 1987/88 fixed target run; preparations for and the taking of the data for (B) E773 (CPT symmetry test) and (C) E799 (rare decay study); and finally (D) R D for a new detector to further study {var epsilon}{prime}/{var epsilon} and rate decays.

Technical Report Wah, Yau W.

Fermilab experiments E731, E773, E799, and E832 are a series of experiments to investigate the physics of CP violation, CPT violation,and rare decays of the neutral kaon system. E731 finished data taking in 1988, during past year the full data set analysis was completed and yielded ([var epsilon][prime]/[var epsilon])[sub 2[pi]]=(7.4 [plus minus] 5.2 [stat] [plus minus] 2.9 [syst] ) [times] 10[sup [minus]4] . The value favors a high top ark mass value within the Standard Model. E773 tests CPT violation by determining ([Delta][phi])[sub 2[pi]] with an accuracy of about 0.5[sup 0].

CP-Violating Asymmetries in eta-prime K and Direct CP Violation Searches with BABAR in Charmless Hadronic B Meson Decays

Technical Report Palombo, F

We present preliminary results of the measurement of branching fractions and CP violating asymmetries in B meson decays to {eta}{prime}K and {phi}K*. We update also the results of the direct CP violation searches with BABAR in charmless hadronic B meson decays.
