Off-shell chromomagnetic dipole moments of light quarks in the SM at and beyond the Z gauge boson mass scale

Abstract

The anomalous chromomagnetic dipole moment, with the gluon off-shell, of the Standard Model (SM) light quarks ([Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]), at the [Formula: see text] gauge boson mass scale, is computed by using the [Formula: see text] scheme. The numerical results disagree with all the previous predictions reported in the literature and show a discrepancy of up to two orders of magnitude in certain situations.
