High Energy Theory Lunch Seminar
"Probing the Standard Model and beyond with (semi)-leptonic meson decays"
Presented by Vincenzo Cirigliano, LANL
Friday, November 2, 2007, 12:00 pm — Bldg 510, room 2-95
Precision studies of leptonic and semi-leptonic decays of light
mesons (pi,K) provide
a sensitive probe of lepton universality, quark-lepton (Cabibbo)
and the ratios of light quark masses.
The Standard Model contribution to these decays provides the
against which one would like to identify or constrain possible new
In this talk I discuss recent improvements in predicting K (pi) ->
ell nu and K -> pi ell nu
decays within the Standard Model, using chiral effective field
I will also briefly discuss the implications of these results on
indirect searches of physics
beyond the Standard Model.
