B-> D* zero-recoil formfactor and the heavy quark expansion in QCD: a systematic study
Paolo Gambino, Thomas Mannel, Nikolai Uraltsev
We present a QCD analysis of heavy quark mesons focussing on the B -> D* formfactor at zero recoil, F_D*(1). An advanced treatment of the perturbative corrections in the Wilsonian…
Charm CP Violation and the Electric Dipole Moments from the Charm Scale
Thomas Mannel, Nikolai Uraltsev
The reported CP asymmetry in D->K^+K^- / pi^+pi^- is argued to be too large to naturally fit the SM. If so, a new source of CP violation is implied in the Delta C=1 sector with a m…
Higher Order Power Corrections in Inclusive B Decays
Thomas Mannel, Sascha Turczyk, Nikolai Uraltsev
We discuss order 1/m_b^4 and 1/m_b^5 corrections in inclusive semileptonic decay of a meson. We identify relevant hadronic matrix elements of dimension seven and eight and esti…
B -> D* at zero recoil revisited
Paolo Gambino, Thomas Mannel, Nikolai Uraltsev
We examine the B -> D* form factor at zero recoil using a continuum QCD approach rooted in the heavy quark sum rules framework. A refined evaluation of the radiative corrections as…
The Two Roads to "Intrinsic Charm" in B Decays
Ikaros Bigi, Thomas Mannel, Sascha Turczyk +1
We describe two complementary ways to show the presence of higher order effects in the 1/m_Q expansion for inclusive B decays that have been dubbed "Intrinsic Charm". Apart from th…
Inclusive semileptonic B decays and the determination of |V_ub|
P. Gambino, P. Giordano, G. Ossola +1
We study the triple differential distribution of B-> Xu l nu, consistently including all perturbative and non-perturbative effects through O(alphas^2 beta_0) and O(1/mb^3). The Fer…
