Heavy Baryons and electromagnetic decays

2000

In this talk I review the theory of electromagnetic decays of the ground state baryon multiplets with oneheavy quark, calculated using Heavy Hadron Chiral Perturbation Theory. The M1 and E2 amplitudes for (S^{*}-> S gamma), (S^{*} -> T gamma) and (S -> T gamma)are separately analyzed. All M1 transitions are calculated up to O(1/��_��^2). The E2 amplitudes contribute at the same order for (S^{*}-> S gamma), while for (S^{*} -> T gamma) they first appear at O(1/(m_Q ��_��^2))and for (S -> T gamma) are completely negligible. Once the loop contributions is considered, relations among different decay amplitudes are derived. Furthermore, one can obtain an absolute prediction for…

Charged Kaon CP Violating Asymmetries vs

2007

We present the next-to-leading order full results in Chiral Pertubation Theory for the charged Kaon K → 3 π slope g CP violating asymmetries. We discuss the constraints that a measurement of these asymmetries would impose on the Standard Model results of e K ′ and search for new physics. We also study the kind of information that such measurement can provide on Im G 8 , Im ( e 2 G E ) and higher order weak couplings.
