R-Parity Violating Contributions to Flavor Changing and CP Violation Effects in Fermion and Sfermion Pair Production

TL;DR

This paper investigates how R-parity violating interactions influence flavor-changing and CP violation effects in fermion and sfermion pair production at leptonic colliders, providing insights into potential observable signals.

Contribution

It analyzes the impact of specific R-parity odd interactions on production rates and CP asymmetries, including detailed distributions for top-charm processes and sensitivity estimates.

Findings

R-parity violating interactions can induce measurable CP asymmetries.

The study estimates the sensitivity reach for detecting these effects.

Dynamical distributions for top decay events are evaluated.

Abstract

We examine the contributions from the R-parity odd interactions, $ \l_{ijk} L_iL_jE_k^c $ and $ \l '_{ijk} L_i Q_j D^c_k$, to the total rates and the CP asymmetry rates in the production of fermion-antifermion (lepton, down and up quark) pairs and slepton-antislepton pairs of different flavors at leptonic colliders. For the top-charm associated production case, we evaluate dynamical distributions for the semileptonic top decay events and estimate the sensitivity reach on the relevant parameters.
