متن کاملAutomatized analytic continuation of Mellin-Barnes integrals
I describe a package written in MATHEMATICA that automatizes typical operations performed during evaluation of Feynman graphs with Mellin-Barnes (MB) techniques. The main procedure allows to analytically continue a MB integral in a given parameter without any intervention from the user and thus to resolve the singularity structure in this parameter. The package can also perform numerical integr...
متن کاملOn the Resolution of Singularities of Multiple Mellin–Barnes Integrals
One of the two existing strategies of resolving singularities of multifold Mellin–Barnes integrals in the dimensional regularization parameter, or a parameter of the analytic regularization, is formulated in a modified form. The corresponding algorithm is implemented as a Mathematica code MBresolve.m E-mail: [email protected] E-mail: [email protected]
متن کاملAMBRE - a Mathematica package for the construction of Mellin-Barnes representations for Feynman integrals
The Mathematica toolkit AMBRE derives Mellin-Barnes (MB) representations for Feynman integrals in d = 4 − 2ε dimensions. It may be applied for tadpoles as well as for multileg and multiloop scalar and tensor integrals. AMBRE uses a loopby-loop approach and aims at lowest dimensions of the final MB representations. It integrates the package MB for the determination of the singularity structure i...
