Nonperturbative region of effective strong coupling
, 2013 In the framework of Poincar covariant quark model the behavior of running coupling constant $ _{s}\left(Q^{2}\right)$ is considered in $Q < 1 \mbox{GeV}$ region. An analysis was carried out for pseudoscalar and vector mesons with lepton decay constants, masses (obtained from model dependent) and nucleon spin rules required to match their ...

What can be measured asymptotically?
Journal of High Energy PhysicsWe consider asymptotic observables in quantum field theories in which the S-matrix makes sense. We argue that in addition to scattering amplitudes, a whole compendium of inclusive observables exists where the time-ordering is relaxed.

Nonperturbative effects in supergravity
, 2006 A promising candidate for a fundamental theory of nature, incorporating both general relativity and quantum mechanics, is string theory. This theory is based on one-dimensional extended objects that move through spacetime. However, string theory is most naturally formulated in ten dimensions.

Sudakov logs and power corrections for selected event shapes
, 2004 I summarize the results of recent studies analyzing perturbative and nonperturbative effects of soft gluon radiation on the distributions of the C-parameter and of the class of angularities, by means of dressed gluon exponentiation.Comment: Talk given at
