Connecting Supersymmetry to Non-Supersymmetric theories: the Gross-Neveu-Yukawa example
Mrigankamauli Chakraborty, Sven-Olaf Moch
We construct a generalized Lagrangian that unifies the Gross-Neveu-Yukawa, Nambu-Jona-Lasinio-Yukawa, and Wess-Zumino models, allowing for arbitrary scalar and fermion flavors in $…
Operator Renormalization using Emergent Supersymmetries
Mrigankamauli Chakraborty, Sven-Olaf Moch
We develop a mechanism that enables supersymmetric Ward identities to be applied in non-supersymmetric theories. These identities are then used to streamline calculations in our ta…
Dimensional Reduction is Supersymmetric at Three Loops
Mrigankamauli Chakraborty, Sven-Olaf Moch
We resolve the long-standing claim that regularisation by dimensional reduction (DR) fails to preserve supersymmetry in Super Yang-Mills (SYM) theories at three loops. Earlier resu…
The asymptotic Hopf Algebra of Feynman Integrals
Mrigankamauli Chakraborty, Franz Herzog
The method of regions is an approach for developing asymptotic expansions of Feynman Integrals. We focus on expansions in Euclidean signature, where the method of regions can also…
