62. Non-factorizable corrections to Higgs production in Vector Boson Fusion

Ming-Ming Long (KIT, TTP)

LHC

Higgs production in Vector Boson Fusion (VBF) has the second largest cross section at the LHC. Its signature on collider is characterized by two energetic jets in the forward region. The previous high-order corrections to VBF Higgs production usually neglect the non-factorizable contribution which is color-suppressed compared to its factorizable counterpart. It was however found in the leading...

11. Precision Drell-Yan phenomenology at N3LO QCD

Xuan Chen (Shandong University)

16/04/2024, 10:00

I would like to report recent progress of phenomenology studies with N3LO QCD corrections. This includes non-local slicing methods applied to relative simple process at the LHC such as Drell-Yan and its application on mW and alphaS determination.

53. Linear power corrections to top quark production processes

We discuss the linear power corrections in $\Lambda_{\text{QCD}}$ to top quark production processes in hadron collisions using renormalon calculus. We show how such non-perturbative corrections can be obtained using the Low-Burnett-Kroll theorem, which provides the first subleading term to the expansion of the real-emission amplitudes around the soft limit. We demonstrate that there are no...

63. Analytic results for massive three-loop form factors

Abilio de Freitas (None)

We present our recent progress in the calculation of massive three-loop form factors in the non-singlet case, using the method of large moments and differential equations derived from them. The expansion coefficients of the solutions to these differential equations correspond to the series of rational numbers multiplying each of the constants appearing in the form factors at different...

97. Revealing Hidden Regions and Forward Scattering

Stephen Jones (CERN)

16/04/2024, 12:00

We discuss a class of Feynman Integrals which contain hidden regions that are not straightforwardly identified using the standard Geometric/Newton polytope approach to the Method of Regions. Using existing analytic results, we analyse the appearance of such regions in forward scattering and on-shell wide-angle scattering and discuss how they can be exposed in both the momentum and parametric...
