FCNC decays of the Higgs bosons in the BGL model

Understand

We consider flavor-changing decays of neutral Higgs bosons in the context of CP-conserving BGL model - a variant of 2HDM Type 3 model suggested by Branco, Grimus and Lavoura - in which tree-level FCNC couplings are suppressed by elements of known fermion mixing matrices.

• The relevant regions of parameter space compatible with experimental restrictions on the SM Higgs properties are studied.
• We also include current bounds on h-> mu tau into consideration.
• In addition, different FCNC decay modes are analyzed for heavier Higgs states (H/A) and conservative estimates for Br(A/H->mu tau) are provided.
