“NNLOCAL: completely local subtractions for color-singlet production in 
hadron collisions”


címmel tartandó szemináriumára.


Kivonat:



The precise theoretical description of particle collisions is of paramount 
importance for fully exploiting the physics potential of the LHC and future 
colliders. The comparison of accurate measurements with high-precision 
calculations will be crucial not only for understanding subtle features of 
the Standard Model, such as the exact shape of the Higgs potential, but may 
also prove vital for finding signs of physics beyond the Standard Model. One 
particular aspect of increasing precision involves computing higher-order 
perturbative corrections to physical observables such as scattering cross 
sections. However, the straightforward application of perturbation theory 
beyond leading order is hampered by the presence of infrared singularities at 
intermediate stages of the calculation. In this talk, we concentrate on 
treating these singularities via the subtraction method and discuss the 
extension of the completely local CoLoRFulNNLO scheme to the case of initial 
state radiation. We then present NNLOCAL, a proof-of-concept Monte Carlo 
program implementing our scheme for the case of color-singlet production in 
hadron collisions.
