DESCRIPTION: Abstract:Any additional SM-like neutral Higgs boson is expect
 ed to be heavy as it would incur extremely tight constraints from electrow
 eak precision tests as well as from its non-observation at the LHC. A clas
 s of flavor models exists which predicts exotic neutral Higgses which\, un
 like the SM Higgs boson\, do not have couplings to VV pair (V = W\,Z)\, an
 d their Yukawa couplings are purely flavor off-diagonal (tc\, tu\, bs\, bd
 \, ... type\, without having any uu\, tt\, bb\, ... type diagonal coupling
 s). By virtue of these two properties they can bypass the stringent constr
 aints mentioned above\, provided the off-diagonal Yukawa couplings are not
  too large to attract some other constraints. Such exotic states can be li
 ght. The sizes of those flavor off-diagonal Yukawas are generally fixed by
  the requirement of correct reproduction of the quark masses and mixing in
  specific flavor models. But in this talk I shall take a model independent
  approach -- simply assume the presence of one such scalar and a pseudo-sc
 alar - both light - having off-diagonal Yukawa couplings whose sizes are r
 estricted by flavor observables\, and focus on how to dig out those states
  from the LHC data.
