# Anatomy of Higgs boson decays into γγ and γZ within the electroweak chiral Lagrangian in the Rξ gauges

@article{Herrero2020AnatomyOH, title={Anatomy of Higgs boson decays into $\gamma$$\gamma$ and $\gamma$Z within the electroweak chiral Lagrangian in the R$\xi$ gauges}, author={Maria Herrero and Roberto A. Morales}, journal={Physical Review D}, year={2020}, volume={102}, pages={075040} }

In this work, we study the Higgs boson decays into two photons and into one photon and one $Z$ gauge boson within the context of the nonlinear effective field theory called the electroweak chiral Lagrangian (EChL). We present a detailed computation of the corresponding amplitudes to one-loop level in the covariant ${R}_{\ensuremath{\xi}}$ gauges. We assume that the fermionic loop contributions are as in the Standard Model and focus here just in the computation of the bosonic loop contributions…
