23. Higgs production at the LHC

Matthew Henry Klein (Southern Methodist University (US))

20/05/2024, 09:00

Since the discovery of the Higgs boson in 2012, the ATLAS and CMS collaborations at the LHC have made precise measurements of a variety of Higgs boson properties, without significant evidence of any BSM behavior. However, large uncertainties are still present on many properties, and many others still remain unmeasured. In this talk, I will summarize the status of Higgs boson measurements and...

27. Pseudoscalar Higgs plus jet production at Next-to-Next-to-Leading Order in QCD

Ciaran Williams (SUNY Buffalo)

20/05/2024, 09:35

We present a calculation of pseudoscalar Higgs production in association with a jet at Next-to-Next-to Leading Order (NNLO) accuracy in QCD. We work in an effective field theory in which $m_t \rightarrow \infty$ resulting in effective operators which couple the pseudoscalar to gluons and (massless) quarks. We have calculated all of the relevant amplitudes for the two-loop, one-loop and...

5. Top-Bottom Interference Contribution to Fully-Inclusive Higgs Production

Felix Eschment (Institut für Theoretische Teilchenphysik und Kosmologie, RWTH Aachen University)

20/05/2024, 10:10

The impact of finite bottom-quark mass effects at next-to-next-to-leading order constitutes one of the leading theory uncertainties of the Higgs production cross section.
In this talk, I will present our evaluation of this contribution. We computed the relevant two-loop master integrals that enter the real-virtual contribution numerically using the method of differential equations. In...

6. NNLO+PS predictions for Higgs production in bottom-quark fusion with MiNNLO

Aparna Sankar

20/05/2024, 11:15

With the growing precision of experimental measurements, combining fixed-order perturbative calculations with parton-shower effects becomes essential for an accurate description of LHC phenomenology. In this talk, we focus on the computation of Higgs production via bottom-quark annihilation ($b \bar{b}H$) at next-to-next-to-leading order (NNLO) in QCD perturbation theory, consistently matched...

7. A first look at two-loop master integrals for ttH

Manfred Kraus (UNAM)

20/05/2024, 11:50

I will present our recent computation of the first set of two-loop master integrals for the top-quark pair production in association with a Higgs boson. Exploiting numerical evaluations in modular arithmetic, we construct a basis of master integrals satisfying a system of differential equations in $\epsilon$-factorized form. We discuss the analytical structure of the differential equations and...
