Two-loop mixed QCD-EW corrections to q q ¯ $$ q\overline{q} $$ → Hg, qg → Hq, and q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$

Autor: Marco Bonetti, Erik Panzer, Lorenzo Tancredi

Publikováno v: Journal of High Energy Physics, Vol 2022, Iss 6, Pp 1-25 (2022)

Abstract We compute the two-loop mixed QCD-Electroweak corrections to q q ¯ $$ q\overline{q} $$ → Hg and its crossed channels qg → Hq, q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$ , limiting ourselves to the contribution of light vi

Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 9, Pp 1-20 (2021)

Abstract We compute ε-expansions around 4 dimensions of a complete set of master integrals for momentum space five-loop massless propagator integrals in dimensional regularization, up to and including the first order with contributions of transcende

Two-loop mixed QCD-EW corrections to gg → Hg

Autor: Marco Bonetti, Erik Panzer, Vladimir A. Smirnov, Lorenzo Tancredi

Publikováno v: Journal of High Energy Physics, Vol 2020, Iss 11, Pp 1-31 (2020)

Abstract We compute the two-loop mixed QCD-Electroweak (QCD-EW) corrections to the production of a Higgs boson and a gluon in gluon fusion through a loop of light quarks. The relevant four-point functions with internal massive propagators are express

Four-loop collinear anomalous dimensions in QCD and N=4 super Yang-Mills

Autor: Bakul Agarwal, Andreas von Manteuffel, Erik Panzer, Robert M. Schabinger

Publikováno v: Physics Letters B, Vol 820, Iss , Pp 136503- (2021)

We calculate the collinear anomalous dimensions in massless four-loop QCD and N=4 supersymmetric Yang-Mills theory from the infrared poles of vertex form factors. We give very precise numerical approximations and a conjecture for the complete analyti

Manifestly dual-conformal loop integration

Autor: Jacob L. Bourjaily, Falko Dulat, Erik Panzer

Publikováno v: Nuclear Physics B, Vol 942, Iss , Pp 251-302 (2019)

Local, manifestly dual-conformally invariant loop integrands are now known for all finite quantities associated with observables in planar, maximally supersymmetric Yang-Mills theory through three loops. These representations, however, are not infrar

The four-loop cusp anomalous dimension from the N=4 Sudakov form factor

Autor: Tobias Huber, Andreas von Manteuffel, Erik Panzer, Robert M. Schabinger, Gang Yang

Publikováno v: Physics Letters B, Vol 807, Iss , Pp 135543- (2020)

We present an analytic derivation of the full four-loop cusp anomalous dimension of N=4 supersymmetric Yang-Mills theory from the Sudakov form factor. To extract the cusp anomalous dimension, we calculate the ϵ−2 pole of the form factor using para

Multiple zeta values in deformation quantization

Autor: Peter Banks, Erik Panzer, Brent Pym

Publikováno v: Banks, P, Panzer, E & Pym, B 2018 ' Multiple zeta values in deformation quantization ' pp. 1-71 . < https://arxiv.org/abs/1812.11649 >

Kontsevich's 1997 formula for the deformation quantization of Poisson brackets is a Feynman expansion involving volume integrals over moduli spaces of marked disks. We develop a systematic theory of integration on these moduli spaces via suitable alg

Lambert-W Solves the Noncommutative $$\varPhi ^4$$-Model

Autor: Raimar Wulkenhaar, Erik Panzer

Publikováno v: Communications in Mathematical Physics. 374:1935-1961

The closed Dyson-Schwinger equation for the 2-point function of the noncommutative $\lambda \phi^4_2$-model is rearranged into the boundary value problem for a sectionally holomorphic function in two variables. We prove an exact formula for a solutio
