A case study of SMEFT $\mathcal{O}(1/{\Lambda }^4)$ effects in diboson processes: $pp\to W^{\pm }({\ell }^{\pm }\nu )\gamma$

Adam Martin

In this paper we explore $pp\to W^{\pm }({\ell }^{\pm }\nu )\gamma$ to $\mathcal{O}(1/{\Lambda }^4)$ in the SMEFT expansion. Calculations to this order are necessary to properly capture SMEFT contributio…
