On lattice, we nonperturbatively renormalize operator RI/MOM scheme cluster-decomposition error reduction (CDER) technique to enhance signal-to-noise ratio renormalization...
We present SynthPop, a new open source, modular population synthesis Galactic modeling software to simulate catalogs of Milky Way stars along any sightline outward from the Sun. Motivated by lack flexibility in existing models, SynthPop is coded entirely python, can be run standalone or as an imported module, and configured json files that allow different model components switched out desired. describe code structure, how generation process runs, use code. also validation testing known...
Background: In stars, carbon is produced exclusively via the $3\alpha$ process, where three $\alpha$ particles fuse to form $^{12}$C in excited Hoyle state, which can then decay ground state. The rate of production stars depends on radiative width be deduced by combining separately measured quantities, one $E0$ branching ratio. ratio exciting state $^{12}$C$(p,p')$ reaction and measuring pair its first $2^+$ Purpose: To reduce uncertainties universe a set proton angular distributions for...
