An effective $SU(3)times SU(3)$ chiral lagrangian, which includes scalar resonances, is used to describe the process $D^+ rar K^- p^+ p^+$ at low-energies. Our main result is a set of five $S$-wave amplitudes, suited to be used in analyses of production data.
Recently we derived a nonlinear U-spin amplitude relation for $D^0to P^+P^-$, $P=pi, K$, predicted to hold up to fourth order U-spin breaking terms of order $10^{-3}$. Here we study a similar relation for $D^0to V^+P^-, V =rho, K^*(892), P = pi, K$,
In the analysis of experimental data on $p p$ (or $bar p p$) elastic differential cross section it is customary to define an average forward slope $b$ in the form $exp{(-b|t|)}$, where $t$ is the momentum transfer. Taking as working example the resul
In this paper, the $Dto P(pi, K)$ helicity form factors (HFFs) are studied by applying the QCD light-cone sum rule (LCSR) approach. The calculation accuracy is up to next-to-leading order (NLO) gluon radiation correction of twist-(2,3) distribution a
In this talk, we investigate $Xi(1690)^-$ production from the $K^-pto K^+K^-Lambda$ reaction wit the effective Lagrangian method and consider the $s$- and $u$-channel $Sigma/Lambda$ ground states and resonances for the $Xi$-pole contributions, in add
We present a study of transverse single-spin asymmetries (SSAs) in $p^uparrow pto J/psi,X$ and $p^uparrow pto D X$ within the framework of the generalized parton model (GPM), which includes both spin and transverse momentum effects, and show how they
