Investigation of the Stability of Some Exotic Four Particle Systems

Abstract

Possible existence of exotic molecules consisting of N=4 unit charge particles is investigated using the Rayleigh-Ritz variational method. Several exotic molecules of the form A − B+B − A+ (e − μ+μ − e+, e − π+π − e+, and μ − π+π − μ+) are found to exist as bound states.
