Using effective Lagrangians, we study the interactions of the state $Z_c(3900)$ with light mesons. We determine the cross sections for the processes $Z_c \pi \rightarrow \bar{D}^{(*)} D^{(*)}$ and as well as the inverse processes. To understand the influence of the medium on the results, we determined the thermal average of the cross-sections.
We propose a non-standard interaction (NSI) in neutrino production to alleviate the tension between the results of the experiments NOvA (NuMI Off-axis $\nu_e$ Appearance) and T2K (Tokai to Kamioka). The NSI is computed through quantum field theory (QFT) formalism and we get perturbative analytic formulas for oscillation probabilities.
In this study, we investigate CP violation in $D_{s} \rightarrow\pi^{-}\pi^{+}K^{+}$ channel using simulations of the Dalitz plot and a technique called Mirandizing.We demonstrate the effectiveness of this approach by visualizing the shape of the CP violation in the Dalitz plot. By analyzing the local population differences, we are able to identify regions where CP symmetry is broken. Our...
In DsPPK selection process we find structure in background , the Challenge is identify and eliminate this structure before start the analysis. We investigate this contamination comes from D0 charm decay, and for testing this hypotesis we will use simulations with RapidSim for testing and confirm our hipotesys.
