49. Fiducial differential cross sections at the LHC and their future applications

Dr Xuan Chen (Universitaet Zuerich (CH))

10/09/2019, 09:00

Fiducial differential cross sections are reliable observables that the LHC is providing more and more precise measurements. From the theory point of view, event generators could simulate the underlying processes and apply the same experimental selection criterion to reduce the systematical errors when comparing with data. I will introduce some of the implementations and simulations from...

52. Top-quark hadroproduction in NNLO QCD

Simone Devoto (UZH)

10/09/2019, 09:30

The study of top-quark production and decay is central in the LHC physics programme, allowing precise tests of the Standard Model and offering a window on possible new physics. Accurate theoretical predictions are crucial for these analyses. In this talk, we report on a new calculation of the next-to-next-to-leading order QCD radiative corrections to the production of top-quark pairs at hadron...

59. NNLO mixed EW-QCD corrections to single vector boson production

In this talk, we outline the computational details to obtain mixed EW-QCD corrections to on-shell production of a single vector boson at the LHC at two-loop level. We use the novel method of differential equation to obtain the pure virtual, real-virtual and double-real master integrals.

75. Mixed EW-QCD corrections to the higgs decay into bottom quarks

After the discovery of the Higgs boson the precise determination of its properties has become a priority. These precision studies often involve the decay of the Higgs boson to bottom quarks, since it is the predominately decay channel. In this talk I will present the calculation of the exact mixed EW-QCD corrections to this decay, which improves upon the existing approximate calculation. In...

64. Mixed EW-QCD two-loop corrections to Drell-Yan production

The Drell-Yan production of charged lepton pairs is one of the key processes measured at hadron colliders. The QCD corrections to the cross-section are known to order $\alpha_s^2$ and electroweak corrections are known to order $\alpha$. The next important step for a better theoretical understanding is the complete calculation of the mixed QCD-EW corrections of order $\alpha_s \alpha$. In this...

66. Mixed QCD x QED Corrections to Drell-Yan Z Production

Ignacio Fabre (ICAS-UNSAM)

10/09/2019, 12:00

When computing perturbative corrections to a process QCD provides the phenomenologically most significant contribution. Nevertheless, because of the similar size of $\alpha_S^2$ respect to $\alpha_{QED}$, for a precision prediction one needs to consider electroweak corrections as well.
In this talk we show how one can obtain the mixed QCDxQED corrections from pure QCD NNLO corrections by...
