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 $…
Four-Loop Gluon Anomalous Dimension of General Lorentz Spin: Transcendental Part
B. A. Kniehl, S. -O. Moch, V. N. Velizhanin +1
We consider the anomalous dimension of the twist-two gluon operator of arbitrary Lorentz spin in the quark flavor singlet sector of a general gauge theory at…
Graphical Functions by Examples
Mrigankamauli Chakraborty, Marco Klann, Sven-Olaf Moch +4
Graphical functions have emerged as a powerful framework for evaluating multi-loop Feynman integrals in perturbative quantum field theory. Defined as massless three-point position-…
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…
Resummation of small-spin singularities in anomalous dimensions of twist-two operators
Alexander N. Manashov, Sven-Olaf Moch, Leonid A. Shumilov
Anomalous dimensions of leading-twist operators in QCD play an important role in precision predictions for high-energy processes, since they govern the scale evolution of parton di…
