Accordingly, Stapp is careful to distinguish between (a) attributing definite spin values in more than one direction to a particle like the neutron and (b) asserting that if the spins of certain pairs of such particles are or were to be measured in this or that direction, a specific mathematical relation will or would be found to hold, on a statistical basis, between the spin values of the members of the pairs.
Stapp is not suggesting that the actual results of spin measurements for one member of a pair of until - recently interacting particles will be affected by the choice of an axis for measuring the spin of the other member of the pair — even if this choice is made after the particles have ceased interacting.
In other words, the possible spin values (with respect to a given axis) for one member of a pair of until - recently interacting particles are not the same in case the spin of the second member of the pair is to be measured along one axis as they would be if the spin of the second particle were to be measured along another axis — even if the selection of the axis for the second particle can be made after the two particles have ceased interacting.

Our understanding of the structure of matter was revolutionized in 1964 when American physicist, Murray Gell - Mann, proposed that a category of particles known as baryons, which includes protons and neutrons, are composed of three fractionally charged objects called quarks, and that another category, mesons, are formed of quark - antiquark pairs.
