m‾c and m‾b from MBc and improved estimates of fBc and fBc(2S)
We extract (for the first time) the correlated values of the running masses m‾c and m‾b from MBc using QCD Laplace sum rules (LSR) within stability criteria where perturbative (PT) expressions at N2LO and non-perturbative (NP) gluon condensates at LO are included. Allowing the values of m‾c,b(m‾c,b)...
