87. Cancellation of NNLO singularities within Local analytic sector subtraction

Gloria Bertolotti (University of Turin)

11/30/22, 4:00 PM

WG1: Higher Order and Resummed Calculations

In this talk, we present the next-to-next-to-leading-order (NNLO) subtraction formula for local cancellation of infrared (IR) divergences for final-state radiation in massless QCD, applying to generic IR-safe observables. Such general and automated algorithm has been developed within the framework of Local analytic sector subtraction. We explicitly show the features of the method and...

151. Precision measurement of photon production

Francesco Giuli (CERN)

11/30/22, 4:20 PM

WG1: Higher Order and Resummed Calculations

I will present the latest results form the ATLAS and CM experiments about photon production measurements at the LHC

41. Feynman integrals and special functions for Hjj production in NNLO QCD

Vasily Sotnikov (University of Zurich (UZH))

11/30/22, 4:40 PM

WG1: Higher Order and Resummed Calculations

Availability of NNLO QCD predictions for scattering processes such as Vjj and Hjj production is essential for the ongoing physics program at the LHC. A crucial missing ingredient is the Feynman integrals contributing to double virtual corrections.  In this talk we present the complete set for the relevant two-loop five-point integrals with one external mass and the associated basis of special...

164. Determination of the Weak Mixing Angle

Rhys Taus (University of Rochester (US))

11/30/22, 5:00 PM

WG1: Higher Order and Resummed Calculations

The weak mixing angle is a key parameter in the electroweak sector of the standard model. Precision measurements of the weak mixing angle allow for testing the standard model and for searching for the effects of new physics.
