Meson mass formula in broken SUN symmetry and its applications

TL;DR: In this article, the Meson mass formula of Borchardt-Mathur-Okubo type is generalized to broken SU N in a form suitable for computer calculation, and the result is applied to SU 5 and SU 6 cases, by assuming two possible assignments: (1) 3.95 or upsilon 5.97 GeV is the new lowest state of J PC = 1 −− member of SU 5 symmetry, and (2)

Retrogress to the past of an expanding universe

TL;DR: Parker's formalis was used in this article as a scalar field model in an expanding universe, and an expression for the probability amplitude of finding zero particles in the past when we start at the present vacuum state, and others.
