D$_{s}$ lifetime, m$_{b}$, m$_{c}$ and |V$_{cb}$| in the heavy quark expansion / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.) ; Uraltsev, N.G. (CERN ; St. Petersburg, INP)
Summary of changes: The discussion of uncertainties in the 1/m.sub(Q) expansion was shortend as the more detailed one was presented in our recent paper ref.[16] and is due in the forthcoming paper [17]. The sections 3 and 4 are then combined..

The baffling semileptonic branching ratio of B mesons / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.) ; Blok, Boris (Technion) ; Shifman, Mikhail A. (Minnesota U.) ; Vainshtein, Arkady I. (Minnesota U.)
The apparent gap between the measured and the expected value for the semileptonic branching ratio of B mesons has become more serious of r the last year. This is due to the improved quality of the data and to the increasing maturity of the theoretical treatment of nonperturbative corrections. [...]

b Quark Physics with 2 .10^9 Z Bosons / Ali, Ahmed (DESY) ; Benson, Donald (Notre Dame U.) ; Bigi, Ikaros I.Y. (Notre Dame U.) ; Hawkings, Richard (CERN) ; Mannel, Thomas (CERN)
It has been suggested to realize a factory for 10^9 Z^0 through a linear e^+e^- collider with polarized beams. Very likely the relevant CP studies for B mesons will already have been performed at the B factories by that time, hence GIGA-Z will be a third generation b physics experiment. [...]

High Power n of $m_b$ in Beauty Widths and $n=5 \to \infty$ Limit / Bigi, Ikaros I.Y. (Notre Dame U.) ; Shifman, Mikhail A. (Minnesota U.) ; Uraltsev, N. (Notre Dame U. ; Minnesota U. ; CERN ; St. Petersburg, INP) ; Vainshtein, Arkady I. (Minnesota U. ; Novosibirsk, IYF)
The leading term in the semileptonic width of heavy flavor hadrons depends on the fifth power of the heavy quark mass. We present an analysis where this power can be self-consistently treated as a free parameter n and the width can be studied in the limit n -> oo. [...]

On measuring the kinetic energy of the heavy quark inside B mesons / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.) ; Grozin, A.G. (Open U., England ; Novosibirsk, IYF) ; Shifman, Mikhail A. (Minnesota U. ; cERN ; St. Petersburg, INP) ; Uraltsev, N.G. (Minnesota U. ; cERN ; St. Petersburg, INP) ; Vainshtein, Arkady I. (Minnesota U. ; Novosibirsk, IYF)
We discuss how one can determine the average kinetic energy of the heavy quark inside heavy mesons from differential distributions in $B$ decays. A new, so-called third, sum rule for the $b\rightarrow c$ transition is derived in the small velocity (SV) limit. [...]

Open questions in charm decays deserving an answer / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.)
A list is given of those open questions concerning the dynamics of charm decays where there exists a strong need for an answer. Such a need is based on lessons to be learnt about QCD -- either in their own right or for a better understanding of $B$ physics -- or on searches for New Physics with a small background from the Standard Model.

CP violation in beauty decays : the standard model paradigm of large effects / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.)
The Standard Model contains a natural source for CP asymmetries in weak decays, which is described by the KM mechanism. Beyond $\epsilon _K$ it generates only elusive manifestations of CP violation in {\em light-}quark systems. [...]

Beauty physics in the next 15 years : an itinerary for a long journey towards an essential goal / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.)
After re-stating why beauty physics is so special and sketching its present status I attempt to map out an itinerary for the next fifteen years. The basic elements are listed for a research program that allows to define and probe the KM unitarity triangle in a manner where the numerical uncertainties are reduced to the few percent level.

Heavy quark distribution function in QCD and the $AC^{2}M^{2}$ model / Bigi, Ikaros I.Y. (CERN ; Notre Dame U.) ; Shifman, Mikhail A. (Minnesota U.) ; Uraltsev, N. (CERN ; St. Petersburg, INP) ; Vainshtein, Arkady I. (Minnesota U. ; Novosibirsk, IYF)
We show that the phenomenological \ACM ansatz is consistent with QCD through order $1/m_b$ in the description of $B\ra l\bar \nu_l+X_u$ and $B\ra \gamma +X_s$ transitions, including their energy spectra and differential distributions. This suggests a concrete realization for the QCD distribution function, the "Roman" function. [...]
