Loop-Less Electric Dipole Moment of the Nucleon in the Standard Model
Th. Mannel, N. Uraltsev
We point out that the electric dipole moment of the neutron in the Standard Model is generated already at tree level to the second order in the weak interactions due to bound-state…
Heavy flavor decays, OPE and duality in two-Dimensional 't Hooft model
I. Bigi, M. Shifman, N. Uraltsev +1
The 't Hooft model (two-dimensional QCD in the limit of large number of colors) is used as a laboratory for exploring various aspects of the heavy quark expansions in the nonlepton…
Non-Abelian Dipole Radiation and the Heavy Quark Expansion
Andrzej Czarnecki, Kirill Melnikov, Nikolaj Uraltsev
Dipole radiation in QCD is derived to the second order in . A power-like evolution of the spin-singlet heavy quark operators is obtained to the same accuracy. In particular, $…
Theoretical Aspects of the Heavy Quark Expansion
N. Uraltsev
I give a brief outline of the theoretical framework for the modern treatment of the strong interaction effects in heavy quark decays, based on first principles of QCD. This model-i…
Chiral Symmetry Breaking, Duality in the \bar{Q}q Channel and b -> c anti-c s Decays
B. Blok, M. Shifman, N. Uraltsev
We address the issue of the quark-hadron duality in the spectral densities induced by the heavy-light quark currents anti-Q q. In the limit m_Q ->oo, m_q ->0 we observe an enhancem…
Operator Product Expansion, Heavy Quarks, QCD Duality and its Violations
Boris Chibisov, R. David Dikeman, M. Shifman +1
The quark (gluon)-hadron duality constitutes a basis for the theoretical treatment of a wide range of inclusive processes -- from hadronic τdecays and R_{e^+e^-}, to semileptonic a…
On the Problem of Boosting Nonleptonic b Baryon Decays
N. G. Uraltsev
The constituent picture of hadrons implies certain quantum mechanical inequalities which must hold in the potential models. Basing on this qualitative consideration I argue that it…
Are IR Renormalons a Good Probe for the Strong Interaction Domain?
Yu. L. Dokshitzer, N. G. Uraltsev
We study the origin of non-analyticity in α_s of a short-distance QCD observable to demonstrate that the infrared renormalons, the same-sign factorial growth of the perturbative ex…
from OPE Sum Rules for Heavy Flavor Transitions
M. Shifman, N. G. Uraltsev, A. Vainshtein
We derive a model-independent upper bound for the axial-vector form factor of the $B\ra D^*$ transition at zero recoil, $F_{B\ra D^*}$. The form factor turns out to be noticeably l…
Heavy Quark Distribution Function in QCD and the ACM Model
I. Bigi, M. Shifman, N. Uraltsev +1
We show that the phenomenological \ACM ansatz is consistent with QCD through order in the description of $B\ra l\bar ν_l+X_u$ and $B\ra γ+X_s$ transitions, including their…
Lifetime, , and in the Heavy Quark Expansion
I. I. Bigi, N. G. Uraltsev
We present some straightforward applications of the QCD heavy quark expansion, stated in previous papers [1-3], to the inclusive widths of heavy flavour hadrons. We address the que…
Weak Annihilation and the Endpoint Spectrum in Semileptonic B Decays
I. I. Bigi, N. G. Uraltsev
A general relationship is formulated between the contributions of `Weak Annihilation' (WA) to inclusive semileptonic decays of heavy flavour hadrons and the matrix elements of four…
A QCD ``Manifesto'' on Inclusive Decays of Beauty and Charm
I. I. Bigi, B. Blok, M. Shifman +2
A selfconsistent treatment of nonperturbative effects in inclusive nonleptonic and semileptonic decays of beauty and charm hadrons is presented. It is illustrated by calculating se…
