### Difference Equations for 5-loop Massive Vacuum Integrals Using Syzygies

In many precision calculations within the Standard Model of particle physics so-called Feynman integrals over loop momenta need to be calculated. Of these integrals, I consider the subclass of fully

### Counting to one: reducibility of one- and two-loop amplitudes at the integrand level

• Physics

A bstractCalculation of amplitudes in perturbative quantum field theory involve large loop integrals. The complexity of those integrals, in combination with the large number of Feynman diagrams, make
