Alternative model to the strong force

Comay published in 1984 a Regular Charge Monopole Theory, that explains magnetic monopoles using a basis which differs from Dirac's formulation. This theory can be derived from a regular Lagrangian density. It proves that electric charges do not interact directly with magnetic monopoles but photons do interact with both electric charges and magnetic monopoles. This result fits the respective experimental results of electrons and hard photons interaction with nucleons. For this reason, it provides a motivation for regarding strong interactions as interactions between monopoles obeying the regular charge-monopole theory.

Explaining the quantum states of Delta++ and Omega- without color force

Comay claims that the quantum state of quarks in baryons is described as a superposition of multiple configuration similarly to the electrons in the atomic shells. This approach enabled him to show that the quantum state of particles like delta++

Explaining the proton spin crisis

Furthermore, Comay showed that the configuration approach explains the paradox called the "proton spin crisis
Nucleon spin structure
Nucleon spin structure describes the partonic structure of nucleon intrinsic angular momentum . The key question is how nucleon spin 1/2 is carried by its constituents, say partons . It was originally expected before the 1980s that quarks carry all of the nucleon spin, but later experiments...

 and R. P. James presented a paradox called Hidden Momentum. In their article they describe a stationary system whose momentum apparently does not vanish. For decades, many scientists tried to solve this paradox, until in 1995 Comay came up with an explanation specifying the explicit nature of this momentum. It turns out that the system also contains a mechanical momentum that stems from a pressure gradient found in a rotating charged liquid that serves as a source for the system's magnetic field

 that predicts two effects: the magnetic AB effect and the electric AB effect. Comay published in 1987 an article that claims that the electric effect cannot exist. He claimed that the derivation of this effect is inconsistent with fundamental principles and it leads to a violation of energy conservation. He also provided an alternative explanation to the magnetic effect that does not use topology. This outcome means that the magnetic AB effect does not prove that topology is an inherent property of quantum mechanics.
