We propose to measure the decay asymmetry parameters in the hadronic weak decays of singly charmed baryons, such as $ldctoldpi^+,Sigma^0pi^+,p bar K_0$, $Xi_c^0toXi^-pi^+$ and $Omega_c^0toOmega^-pi^+$. The joint angular formulae for these processes are presented, and are used to extract the asymmetry parameters in $ee$ annihilation data. Base on the current $ldc$ data set collected at BESIII, we estimate the experimental sensitivities to measure the parameters $alpha_{ldpi^+}$ for $ldctoldpi^+$, $alpha_{Sigma^+pi^0}$ for $ldctoSigma^+pi^0$ and $alpha_{usigpi^+}$ for $ldctousigpi^+$.
We examine the processes $e^+ e^-longrightarrow W^+ W^-$ and $Z^0 Z^0$ in the context of the $SP(6)_Lotimes U(1)_Y$ model. We find that there are significant deviations in the total cross sections $sigma (s)$ from the standard model results due to th
We study, at leading order in the large number of colours expansion and within the Resonance Chiral Theory framework, the odd-intrinsic-parity $e^+ e^- rightarrow pi^+ pi^- (pi^0, eta)$ cross-sections in the energy regime populated by hadron resonanc
We correct an important misprint in the journal version of our earlier work on New Jet Cluster Algorithms: Next-to-leading Order QCD..., published in Nucl. Phys. B 370 (1992) 310, which may have lead to an incorrect parametrisation of the leading ord
We point out that the fragmentation of a strange quark into nucleons versus antinucleons is not necessarily identical $D_{p/s}(z,Q^2) eq D_{bar p/s}(z,Q^2)$, even though the perturbative contributions from gluon splitting and evolution are $p leftri
The usual interpretation of Bose-Einstein correlations (BEC) of identical boson pairs relates the width of the peak in the correlation function at small relative four-momentum to the spatial extent of the source of the bosons. However, in the tau-mod
