(a) Calculate to lowest order the decay rate \(h \rightarrow b \bar{b}\).

(b) Calculate the decay rate for \(h \rightarrow g g\). (Hint: This problem requires a one-loop calculation and some care and effort.)

(c) Draw the lowest order diagrams contributing to the decay \(h \rightarrow \gamma \gamma\).
