+== Model Description ==
+
+In addition to the SM particle contents, we add one heavy scalar which might come from the second doublet etc. We focus on the effective couplings to the vector bosons, which are related to EWSB, and add following operators with both dim-6 and dim-4:
+
+{{{#!latex
+\begin{align*}
+    \mathcal{L}_6 =& g_{6,H}^{WW} (\partial_\nu H)W^{\dagger}_{\mu} W^{\mu\nu} + h.c. + g_{6,H}^{\prime WW} H W^{\mu\nu}W^\dagger_{\mu\nu} \nonumber \\
+    & + g_{6,H}^{ZZ} (\partial_\nu H) Z_\mu Z^{\mu\nu} + h.c. + g_{6,H}^{\prime ZZ} H Z^{\mu\nu}Z_{\mu\nu} +\nonumber \\
+    & + g_{6,H}^{Z\gamma} (\partial_\nu H) Z_\mu F^{\mu\nu} + g_{6,H}^{\prime Z\gamma} F^{\mu\nu}Z_{\mu\nu} \nonumber \\
+    & + g_{6,H}^{\gamma\gamma} H F^{\mu\nu}F_{\mu\nu}
+\end{align*}
+}}}
+and
+{{{#!latex
+\begin{align*}
+    \mathcal{L}_4 = g_{4,H}^{WW}g^{\mu\nu} H W^+_\mu W^-_\nu + g_{4,H}^{ZZ}g^{\mu\nu} H Z_\mu Z_\nu
+\end{align*}
