In early work, Samuel used particle field theory methods to obtain results in statistical mechanics.
[5] Samuel went on to treat certain interacting statistical mechanics systems using perturbative field theory.
Their lattice QCD computation[7] of the meson mass spectrum agreed well with the one in nature with the exception of the pion mass, where it is known that treating spin perturbatively is not a good approximation due to approximate spontaneous breaking of chiral symmetry.
[8] Samuel and Moriarty went on to make mass predictions for hadrons involving the bottom quark that had not yet been produced in accelerators.
[10] Samuel's most important work in supersymmetry arose in a collaboration with the theorist Julius Wess in a publication called "Secret Supersymmetery.
"[11] In this work, the two physicists constructed an effective low-energy theory of the supersymmetric generalization of the Standard Model of particle physics for the situation in which supersymmetry is spontaneously broken.
[12][13] This allowed the computation of the scattering of string states when the on-shell condition E2 = m2c4 + p2c2 is analytically continued so that it no longer holds.
[16] He observed a number of interesting phenomena that can occur in such systems including a self-induced Mikheyev–Smirnov–Wolfenstein effect and a parametric resonant conversion.
