The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Doublet Models (2HDMs). data experiments been statistically combined. results are interpreted within 2HDM Type I II benchmark scenarios. No significant excess has observed when compared to Standard Model background prediction, combined exclude large regions model parameter space. Charged with mass below 80 \({\rm GeV}/c^{2}\) (Type scenario) or 72.5 scenario,...
A new technique is applied to data collected at the $\ensuremath{\psi}(3770)$ resonance derive charmed-$D$-meson branching fractions without relying on measurement of $D$-production cross sections. Measurements are presented for three decay modes ${D}^{0} ({K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}, {D}^{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}, \mathrm{and} {K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$ and four...
Evidence is presented for a narrow state, called \ensuremath{\xi}, in the decay modes J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\xi}, \ensuremath{\xi}\ensuremath{\rightarrow}${K}^{+}$${K}^{\mathrm{\ensuremath{-}}}$, and \ensuremath{\xi}\ensuremath{\rightarrow}${K}_{S}^{0}$${K}_{S}^{0}$.

Measurements of the semileptonic branching ratios charmed ${D}^{+}$ and ${D}^{0}$ mesons are presented, from data collected at $\ensuremath{\psi}(3770)$ in Mark III detector SPEAR. From a sample events kinematically selected as ${D}^{+}{D}^{\ensuremath{-}}$ or ${D}^{0}{\overline{D}}^{0}$ pairs, $R({D}^{+}\ensuremath{\rightarrow}{e}^{+}+X)=(17.0\ifmmode\pm\else\textpm\fi{}1.9\ifmmode\pm\else\textpm\fi{}0.7)%$...
We severely criticize the consuetudinary analysis of afterglows gamma-ray bursts (GRBs) in conical-ejection fireball scenarios. argue that, instead, recent observations imply that long-duration GRBs and their are produced by highly relativistic jets cannonballs (CBs) emitted supernova explosions. The CBs heated collision with shell. GRB is boosted surface radiation emit as they reach transparent outskirts exiting further decelerate sweeping up interstellar matter (ISM). early X-ray afterglow...
