WebMotivated by recent results from Higgs searches at the Large Hadron Collider, we consider possibilities to enhance the diphoton decay width of the Higgs boson over the Standard Model expectation, without modifying either its production rate or the partial widths in the WW and ZZ channels. Webifies the probability of finding different values of the pa-rameters. These probabilities would emerge from string theory and the weight encodes the shape of the string landscape. Let us call this weight ρ(v,Γi,gi) where v is the Higgs vacuum expectation value, Γi are the Yukawa couplings, and gi stands for the gauge couplings and all
