[Theory-seminars] Seminar Monday, Nov 25, L102, 1p.m.

[Cesar Fernandez-Ramirez]

Dear all,

we will have a Theory Center Seminar on Monday, Nov 25,
CEBAF Center, Room L102, 1:00 p.m.

Speaker: Emilie Passemar (Los Alamos National Laboratory)

Title: Eta -> 3 pi and Light Quark Masses 

Abstract: Recently, several experimental collaborations have invested considerable
effort into new and more precise measurements of the eta -> 3 pi decays.
These experimental advances require revisiting the corresponding
theoretical analyses. In this talk, we present a new calculation of the
eta -> 3 pi decay amplitude relying on dispersive methods. We show how the
study of this decay allows one to extract a fundamental parameter of the
Standard Model, namely the quark mass ratio
(m_d^2-m_u^2)/(m_s^2-\hat{m}^2), with good precision. We then discuss the
possibility of extracting the individual light quark masses.
