just looking at the standard model, which describes a host of fundamental particles and bosons, one could assume that the SM is a particle model. however, most of what i read appears to indicate that particles are merely "excitations" or manifestations of a field, and it has been stated on this forum that SM is a field theory. this field explanation seems to make sense, since what we consider fundamental "particles" like quarks and leptons, are all point particles with zero volume - ie, there is "no-thing" there, only properties. at the same time, science has no idea of how a field operates, and apparently is built on "spooky action at a distance", since no particles ever actually come into direct contact to impart changes in momentum or energy - they conduct these exchanges via "virtual" particle exchange (magic?). what is your particular view of this? is SM a particle theory or a field theory? thanks.
