Calculations with off-shell matrix elements, TMD parton densities and TMD parton showers
A new calculation using off-shell matrix elements with TMD parton densities supplemented with a newly developed initial state TMD parton shower is described. The calculation is based on the KaTie package for an automated calculation of the partonic process in high-energy factorization, making use of TMD parton densities implemented in TMDlib. The partonic events are stored in an LHE file, simil...
متن کاملFully Off-shell Effective Action and its Supersymmetry in Matrix Theory
As a step toward clarification of the power of supersymmetry (SUSY) in Matrix theory, a complete calculation, including all the spin effects, is performed of the effective action of a probe D-particle, moving along an arbitrary trajectory in interaction with a large number of coincident source D-particles, at one loop at order 4 in the derivative expansion. Furthermore, exploiting the SUSY Ward...
متن کاملFully Off-shell Effective Action and its Supersymmetry in Matrix Theory II
In a previous work, we computed the fully off-shell effective action Γ and the corresponding quantum-corrected supersymmetry (SUSY) transformation operator δǫ for the so-called source-probe configuration in Matrix theory at one loop at order 4 in the derivative expansion, and showed that they satisfy the SUSY Ward identity δǫΓ = 0. In this article, starting from the most general form of Γ, we d...
متن کاملOff-shell SUSY Invariant Actions in Four Dimensions
We propose N = 4 twisted superspace formalism in four dimensions by introducing Dirac-Kähler twist. In addition to the BRST charge as a scalar counter part of twisted supercharge we find vector and tensor twisted supercharges. By introducing twisted chiral superfield we explicitly construct off-shell twisted N = 4 SUSY invariant action. We can propose variety of supergauge invariant actions by ...
متن کاملAsymptotic Bethe Ansatz S-matrix and Landau-Lifshitz type effective 2-d actions
Motivated by the desire to relate Bethe ansatz equations for anomalous dimensions found on the gauge theory side of the AdS/CFT correspondence to superstring theory on AdS5 × S5 we explore a connection between the asymptotic S-matrix that enters the Bethe ansatz and an effective two-dimensional quantum field theory. The latter generalizes the standard “non-relativistic” LandauLifshitz (LL) mode...
