	1	Preface显示文摘The standard model(SM)in particle physics has been successfully tested by the present experimental observations.The SM consists of electroweak unification theory and quantum chromodynamics(QCD)theory with light quarks(u;d;s)and heavy quarks(c;b;t)as its fundamental components.Usually,these quarks are named as the light flavor and the heavy flavor.In addition to quarks,there are intermediate gauge bosons and gluons for mediating	Tao Huang	2014	Chinese Science Bulletin2014，59，29：	0
	2	The B→D^()lv_l decays in the pQCD approach with the Lattice QCD input显示文摘In this paper, we studied the semileptonic decays B→D^(()l-_l) by using the ‘‘pQCD+Lattice QCD'' method. We made the extrapolation for the six relevant form factors by using the input values obtained from the p QCD factorization approach in the low q^2 region of 0≤q2≤m_t^2 and the lattice QCD input at the endpoint q^2=q_(max)~2. We then calculated the ratios R(D) and R(D)* of the branching ratios B(B→D^(()l-_l) )and found numerically that(1) the ‘‘pQCD+ Lattice QCD'' predictions for the branching ratios B(B→D^(()l-_l))agree well with the measured values within one standard deviation; and(2) the‘‘pQCD+Lattice QCD'' predictions for the ratios R(D) are R(D)=0:337_(0.037)^(0.038)and R(D)=0:269_(0.020)^(0.021 ); they agree with the data within 2δ deviation, in other words, one can explain the ‘‘R(D)-puzzle'' in the framework of the Standard Model.
