Description

We revisit charged lepton flavor violating (CLFV) scattering ${\ell }_{i}N\to {\ell }_{j}X$ mediated by scalar interaction. We point out that a new subprocess ${\ell }_{i}g\to {\ell }_{j}g$ via the effective interactions of CLFV mediator and gluon gives large contribution. Furthermore, in the light of quark number conservation, we consider quark pair-production processes ${\ell }_{i}g\to {\ell }_{j}Q\overline{Q}$ ($Q$ denotes heavy quarks) instead of ${\ell }_{i}Q\to {\ell }_{j}Q$. We discuss model discrimination by analyzing final state distributions.
