The Belle II Physics Book
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB e+e- collider. Belle II collected its first collisions in 2018, and is expected to operate for

Calculation of the quark and gluon form factors to three loops in QCD
We describe the calculation of the three-loop QCD corrections to quark and gluon form factors. The relevant three-loop Feynman diagrams are evaluated and the resulting three-loop Feynman integrals
The Sudakov form factor at four loops in maximal super Yang-Mills theory
A bstractThe four-loop Sudakov form factor in maximal super Yang-Mills theory is analysed in detail. It is shown explicitly how to construct a basis of integrals that have a uniformly transcendental
Systematics of the cusp anomalous dimension
A bstractWe study the velocity-dependent cusp anomalous dimension in supersymmetric Yang-Mills theory. In a paper by Correa, Maldacena, Sever, and one of the present authors, a scaling limit was
The three-loop form factor in $ \mathcal{N} = {4} $ super Yang-Mills
A bstractIn this paper we study the Sudakov form factor in $ \mathcal{N} = {4} $ super Yang-Mills theory to the three-loop order. The latter is expressed in terms of planar and non-planar loop
Two-body non-leptonic heavy-to-heavy decays at NNLO in QCD factorization
A bstractWe evaluate in the framework of QCD factorization the two-loop vertex corrections to the decays B¯s→Ds∗+L−$$ {\overline{B}}_{(s)}\to {D}_{(s)}^{\left(\ast \right)+}{L}^{-} $$ and Λb → Λc+L−,
