Bounds on the anomalous $HZ\gamma$ vertex arising from the process $e^{+}{e}^{-}\to {\tau }^{+}{\tau }^{-}\gamma$

A. Gutierrez-Rodriguez, J. Montano, M. A. Perez

We obtain limits on the anomalous coupling $HZ\gamma$ through data published by the L3 Collaboration on the process $e^{+}{e}^{-}\to {\tau }^{+}{\tau }^{-}\gamma$. Our analysis leads to bounds on this coupling o…
