Search for the Lepton Flavour Violating Higgs decay H --> tau mu at Hadron Colliders

الأصل · EN

We study the prospects to detect at hadron colliders the Lepton Flavour Violating Higgs decay H --> tau mu, which can reach substantial branching fractions in several extensions of the SM. Among them, the generic two higgs doublet model can be taken as a representative case where B.R.(H --> tau mu) can reach values of order 10-1-10-2. Bounds on the LFV factor kappatau mu of order 0.8-1.7 can be derived at 95% c.l. at Tevatron Run-2 with 4 fb-1 for mₕ = 110-150 GeV.
