All Two-Loop Feynman Integrals for Five-Point One-Mass Scattering
We compute the complete set of two-loop master integrals for the scattering of four massless particles and a massive one. Our results are ready for phenomenological applications, removing a major obstacle to the computation of complete next-to-next-to-leading order QCD corrections to processes such as the production of a H/Z/W boson in association with two jets at the LHC. Furthermore ...
Muonic X-rays peer into brooch from Roman city
Using Muon Induced X-ray Emission, researchers could reveal the inner composition of a knob-bow fibula, excavated at Augusta Raurica in northern Switzerland.
Making sense of the muon’s misdemeanours
An exotic atom called muonium could explain why muons won’t stick to the rules, believe researchers using the Swiss Muon Source at Paul Scherrer Institute PSI.
