at Universe ( 1001-Primera-119 - Nave. Exp. Sala de Reuniones )
Description
Blackboard introduction to the loop-tree duality (LTD) and four-dimensional unsubtraction (FDU), as new perturbative method in quantum field theory, with the following programme:
- Introduction to regularization in QFT in general and DREG, integration in d dimensions, poles, loops. 
- LTD theorem: poles of the Feynman propagators, Cauchy theorem, IR and UV singularities in the loop momentum space.
- FDU: virtual contributions, real contributions, IR cancellation, UV cancellation, self-energies, and the massive case.
