The influence of dimension eight operators on weak matrix elements
Mu dimension calculation matrix elements scale dimensional regularization
2014/12/22
I describe recent work with V. Cirigliano and E. Golowich on the effect of dimension eight operators on weak nonleptonic amplitudes. The basic mesage is that there is an inconsistency in the way that ...

neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...
Tensorial form and matrix elements of the relativistic nuclear recoil operator
Isotope shifts, mass shift, relativistic nuclear recoil
2011/8/31
Within the lowest-order relativistic approximation (∼ v2/c2) and to first order in me/M, the tensorial form of the relativistic corrections of the nuclear recoil Hamiltonian is derived, opening ...
K --> pi pi matrix elements from mixed action lattice QCD
K --> pi pi matrix elements mixed action lattice QCD
2011/1/7
We present a new method for determining K --> pi pi matrix elements from lattice simulations that is less costly than direct simulations of K --> pi pi at physical kinematics. It improves, however, up...
