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

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

The anomalous chromomagnetic dipole moment, with the gluon off-shell, of the Standard Model (SM) light quarks ( u , d , s , c and b ), at the Z gauge boson mass scale, is computed by using the MS ¯ scheme. The numerical results disagree with all the previous predictions reported in the literature an...

Zusammenfassung:The anomalous chromomagnetic dipole moment, with the gluon off-shell, of the Standard Model (SM) light quarks ( u , d , s , c and b ), at the Z gauge boson mass scale, is computed by using the MS ¯ 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.
