Flavor changing neutral current decays $t\to cX$ ($X=\gamma ,g,Z,H$) and $t\to c\bar{\ell }\ell$ ($\ell =\mu ,\tau$) via scalar leptoquarks

The flavor changing neutral current decays $t\to cX$ ($X=\gamma ,g,Z,H$) and $t\to c\bar{\ell }\ell$ ($\ell =\mu ,\tau$) are studied in a renormalizable scalar leptoquark (LQ) model w…
