Angularity Distributions at One Loop with Recoil
/ Budhraja, Ankita (IISER, Bhopal) ; Jain, Ambar (IISER, Bhopal) ; Procura, Massimiliano (Vienna U. ; CERN)
Angularities are a general class of event shapes which depend on a continuous parameter \(b>-1\) that interpolates between recoil-insensitive observables like thrust and observables that are maximally sensitive to recoil effects like jet broadening. We present the first analytic calculations for angularity singular cross section at one-loop order taking into account the recoil effects, irrespective of the exponent b, within the Soft Collinear Effective Theory (SCET) framework. In the differential cross section, these recoil effects contribute to new terms which can have important consequences on resummation of the large logarithms. [...]

We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g-2$ Theory Initiative to update the Standard Model prediction..

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure constant $\alpha$ and is broken down into pure QED, electroweak, and hadronic contributions. [...]

Dispersion relations for hadronic light-by-light scattering and the muon $g – 2$
/ Procura, Massimiliano (CERN) ; Colangelo, Gilberto (U. Bern, AEC) ; Hoferichter, Martin (Washington U., Seattle) ; Stoffer, Peter (Bonn U. ; Bonn U., HISKP ; UC, San Diego)
The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g – 2)$_μ$ come from hadronic effects, and in a few years the subleading hadronic light-by-light (HLbL) contribution might dominate the theory error. We present a dispersive description of the HLbL tensor, which is based on unitarity, analyticity, crossing symmetry, and gauge invariance. [...]

NLO angularity distributions with recoil
/ Budhraja, Ankita (IISER, Bhopal) ; Jain, Ambar (IISER, Bhopal) ; Procura, Massimiliano (Vienna U. ; CERN)
Angularities are event shapes whose sensitivity to the splitting angle of a collinear emission is controlled by a continuous parameter $b$, with $ -1 < b < \infty$. When measured with respect to the thrust axis, this class of QCD observables includes thrust ($b=1$) and jet broadening ($b=0$), the former being insensitive to the recoil of soft against collinear radiation, while the latter being maximally sensitive to it.
