optical theoremparton modelpomeranchuk particlesquarksregge cutsThere is a J = 0 a right-signature fixed pole in the amplitude T ++−−( γ1 γ2→ γ1 γ2) for forward elastic photon-photon scattering. When one of the photons is real ( q 1 2 = 0), the pole residue is an ...
For the partial fraction expansion, pfeLaplace uses the MATLAB function residue which find coefficients of the expansion as well as the poles of X(s) (the residue r(i) in the vector r corresponds to the expansion term for the pole p(i); for instance the residue r(1)=8 corresponds to...
The residue g3(Pc(4440)), except for Fits 3 and A, is smaller than g3(Pc(4312)) and g3(Pc(4457)). This supports that the Pc(4440) is not D¯∗Σc molecule origin. For the Pc(4457), we do not find poles close to the ’strcuture’ as indicated by the data in Fits A...

In this article, we consider meromorphic univalent functions f in the unit disc of the complex plane having a simple pole at z = α ∈ (0, 1) with nonzero residue b at z = α . In 1969, P.N. Chichra proved an area theorem for such functions. In this note, we generalize this...
