By employing the perturbative QCD(pQCD) factorization approach, we calculate the new physics contributions to the four B→Kη()decays in the Standard Model(SM)
The unitary correlation operator method(UCOM) and the similarity renormalization group theory(SRG)are compared and discussed in the framework of the no-core Mon
To meet the measurement demands on small-mass radiocarbon(carbon content at 10-6g level) which are becoming increasingly significant, Xi’an-AMS has made improv
