TL;DR: Using data from the FOCUS experiment, the D+π− and D0π+ invariant mass distributions are analyzed to find evidence for broad structures over background in both the neutral and charged final state.

TL;DR: In this article, a search for CPT violation in neutral charm meson oscillations was performed and the 95% confidence level limit is −0.0068 ξ ) y −(Im ξ) x N ( x, y, δ )(Δ a 0 + 0.6Δa Z ) −16 ǫ −16 Á −16 n −16 −16

TL;DR: In this paper, the authors present a measurement of the top quark mass in the dilepton channel based on approximately 370 pb{sup -1} of data collected by the D0 experiment during Run II of the Fermilab Tevatron collider.

TL;DR: In this article, the authors performed a Dalitz plot analysis of the Cabibbo favored decay D{sup +} {yields} K{sup -{pi}{sup +}{pi}{ sup +}, and used 53653 Dalitzplot events with a signal fraction of approximately 97%.

TL;DR: In this article, the authors search for T violation in charm meson decays using the four-body decay channels D 0 → K − K + π − π +, D + → K S 0 K+ π− π+, and D s → KS 0 K−K+π−π+ +, and find the asymmetry values to be A T viol (D 0 ) = 0.010 ± 0.057 ( stat.
