OPE-based Methods in Nonperturbative QCD
M. Shifman
I describe the inception and development of nonperturbative OPE-based methods in hadronic physics, such as the SVZ sum rules, inverse heavy quark mass expansion (IHQME) and so on a…

Exact Results in Non-Supersymmetric Large N Orientifold Field Theories
A. Armoni, M. Shifman, G. Veneziano
We consider non-supersymmetric large N orientifold field theories. Specifically, we discuss a gauge theory with a Dirac fermion in the anti-symmetric tensor representation. We argu…

Lifetimes of Charmed Hadrons Revisited. Facts and fancy
Boris Blok, Michael Shifman
The problem of the hierarchy of lifetimes of charmed hadrons is reviewed. The QCD-based theory of preasymptotic effects in inclusive weak decays dating back to the beginning of the…
