Evaluation of the second virial coefficient for the Mie potential using the method of brackets

Ivan Gonzalez, Igor Kondrashuk, Victor H. Moll +1

The second virial coefficient for the Mie potential is evaluated using the method of brackets. This method converts a definite integral into a series in the parameters of the probl…

Mellin-Barnes and the method of brackets

Ivan Gonzalez, Igor Kondrashuk, Victor H. Moll +1

The method of brackets is a method for the evaluation of definite integrals based on a small number of rules. This is employed here for the evaluation of Mellin-Barnes integral. Th…

Analytic expressions for Debye functions and the heat capacity of a solid

Ivan Gonzalez, Igor Kondrashuk, Victor H. Moll +1

Analytic expressions for the -dimensional Debye function are obtained by the method of brackets. The new expressions are suitable for the analysis of the asymptotic behavior of…

Multi-fold contour integrals of certain ratios of Euler gamma functions from Feynman diagrams: orthogonality of triangles

Ivan Gonzalez, Igor Kondrashuk, Eduardo A. Notte-Cuello +1

We observe a property of orthogonality of the Mellin-Barnes transformation of the triangle one-loop diagrams, which follows from our previous papers [JHEP {\bf 0808} (2008) 106, JH…

Explicit calculation of multi-fold contour integrals of certain ratios of Euler gamma functions. Part 1

Ivan Gonzalez, Bernd A. Kniehl, Igor Kondrashuk +3

In this paper we proceed to study properties of Mellin-Barnes (MB) transforms of Usyukina-Davydychev (UD) functions. In our previous papers [Nuclear Physics B 870 (2013) 243], [Nuc…

Pochhammer Symbol with Negative Indices. A New Rule for the Method of Brackets

Ivan Gonzalez, Lin Jiu, Victor H. Moll

The method of brackets is a method of integration based upon a small number of heuristic rules. Some of these have been made rigorous. An example of an integral involving the Besse…
