Cluster algebras and scattering diagrams appear in diverse areas of mathematics and physics including total positivity, Seiberg duality, statistical physics models, noncommutative geometry, tropical ...

Two new pion-nucleon resonances, one in each of the two isotopic states, have been found at the following mass values: M12=2.65±0.01 GeV and M32=2.85±0.01 GeV. A search for other resonances at higher ...
