TL;DR: In this article, the authors considered the theoretical and experimental constraints on two-Higgs-doublet models, focusing on the parameter space relevant to explain the present muon g-2 anomaly, Delta alpha(mu), in four different types of models, type I, II, lepton specific and flipped.

TL;DR: In this article, a new experiment was proposed to measure the running of the electromagnetic coupling constant in the space-like region by scattering high-energy muons on atomic electrons of a low-Z target through the elastic process.

TL;DR: In this article, the authors evaluate the master integrals for the two-loop, planar box-diagrams contributing to the elastic scattering of muons and electrons at next-to-next-to leading-order in QED.

TL;DR: In this article, a new experiment was proposed to measure the running of the fine-structure constant in the space-like region by scattering high-energy muons on atomic electrons of a low-Z target through the process, measured as a function of the squared momentum transfer.
