5. Ultramodern Problems in Particle Physics and a Possible Remedy by
Svadavada (24.12.12):
Kight from the birth of modern science, people have aimed for search. mg out the most ulomentary consutuents of various forns of watter, Lot of theoretical and experimental work has been done till to-day to understand the properties of matter at microscopic level but there are many difficult and almost" unsurmountable problems in this field.
As we live emphasized carlier, all forms of matter can he understood in terms of four well known interactions through which they influence each other. Out of these four, the most difficult and the most interesting inter. action is the strong or nuclear interaction. The particles which undergo this interaction are known as hadrons. To study then various models have been developed and dillerent types of scattering processes have been studied tising the high energy machines. Different Modles have been suggested to explain different experimental observations. Although there are so many models but the important ones are parton modle, quark model and boot. strap model. Partons are assumed to be paint-like coostituents of handrons, Their number in a hadron may he finite or infinite depending upon some conditions. However they cannot be observed in the laboratory so it is simply a model and is meant for explaining electron-hadron scattering experiment. Quark model is based on some symmetry properties known as SU, group symmetry. In this model every hadron is assumed to be consti. tut.d from three elementary quarks and antiquarks. It is still controversial whether we can observe them or not in the laboratory. Finally in the bootstrap model one assumes that no hadron is elementary, all are equally fundamiental. We have to emphasize here that all these are models and so they explain different attributes (and sometimes same). There is a lot of controversy about the region of validity of each one of these models and the interconnection between theni.
ff we just unfold the Jaina philosophy in this context, we find that syādavada muy he of immense help in this case. The idea of Ananta Paryaya of Pudgala (Pudgala is a name for matter in Jainiam, 'pud' to combine and "gal' to dissoc ate) is equally significant in this situation. It may be that each model describes only one part of reality and in cach case none of the so called fundamental particle is conceivable by us and so is undetectable in the laboratory
Each description is then a model and a model is a model after all. Ezich one describing one aspect of reality from one point of view and so there is no controversy. Some people talk of a dualism between the quark model (in configuration suce) and the parton model (in the momentum space). But syadlaveda and the ideas of ananta paryāya of matter appears to
