On the pionnucleon coupling constant
, 1992
"... In view of the persisting misunderstandings about the determination of the pionnucleon coupling constants in the Nijmegen multienergy partialwave analyses of pp, np, and pp scattering data, we present additional information which may clarify several points of discussion. We comment on several recen ..."

Dynamical gauge coupling constants
 Lectures given at the 195 Trieste Summer School, hepph/9601241
"... In string theory the coupling parameters are functions of moduli fields. The actual values of the coupling constants are then dynamically determined through the vacuum expextation values of these fields. We review the attempts to connect such theories to low energy effective field theories with real ..."

Status of the strong coupling constant
 Proc. XXVII Int. Conf. on High Energy Physics
, 1996
"... The current status of measurements of the strong coupling constant from different reactions is reviewed. Including new results presented at the 1996 ICHEP conference, a global average αs(MZ) =0.118 ± 0.003 is obtained. Plenary talk given at the ..."

On the value of coupling constant.
, 2008
"... Using an analogy between Bogomol’nyi bound and the harmonic oscillator in quantum mechanics we propose a possible explanation of the coupling constant numerical value at the grand unification scale. It is found to be 1/8π. According to the recent precise experiments [1], the running coupling constan ..."

Uncertainties in Coupling Constant Unification
 Mad/PH/711, Bulletinboard: hepph@xxx.lanl.gov
, 1992
"... The status of coupling constant unification in the standard model and its supersymmetric extension are discussed. Uncertainties associated with the input coupling constants, mt, threshold corrections at the low and high scales, and possible nonrenormalizable operators are parametrized and estimated. ..."

The Liouville Coupling Constants
"... For the general operator product algebra coefficients derived by Cremmer Roussel Schnittger and the present author with integer screening numbers, the coupling constants determine the factors additional to the quantum group 6j symbols. They are given by path independent products over a two dimension ..."

Running coupling constants . . .
"... The topic of this talk is the renormalization group flow in twodimensional field theories that are coupled to gravity. I will explain the basic ideas at the example of the sineGordon model. I will define in a minute, what is meant by scaledependent coupling constants in theories with gravity, whe ..."

Induced Pseudoscalar Coupling Constant
, 1998
"... The recent TRIUMF experiment for µ − p → nνµγ gave a surprising result that the induced pseudoscalar coupling constant gP was larger than the value obtained from µ − p → nνµ experiment as much as 44 %. Reexamining contribution of the axial vector current, we found an additional term to the matrix el ..."

"... We try to review the main current ideas and points of view on the running coupling constant in QCD. We begin by recalling briefly the classic analysis based on the Renormalization Group Equations with some emphasis on the exact solutions for a given number of loops, in comparison with the usual appr ..."
