Hello.
One basic question.
What properites that quarks have which their "compound" forms [protons/neutrons] don't have and vice-versa? That is, a proton may have some property or characteristic and the quarks might not be having that. So something which is NOT available at the components level is present at the 'whole' level [or vice-versa].
Are they any properties/characteristics like that?
The intrinsic properties of quarks are [from wikipedia] - spin, mass, electric charge & colour charge.
Now, 3 quarks form a proton. And the intrinsic properties of a nucleon - spin, mass & electric charge.
Mass, spin & charge are quantitative. they add up or get subtracted. So the 'whole' formed [proton/neutron] would have the property which is sum of the components' properties. And other numbers like - baryon no., charm, etc. - are again quantitative.
Colour charge is of course not available at the nucleon level because of they are used to explain the strong force - which forms the 'whole' itself.
So is there any specific characteristic/property that is present at one level [individual or whole level] but not at other?
NB - When I say characteristic/property, I am not referring to the behaviour of the referred object. the behaviour, say deflection in a magnetic field, is because of a property like charge. Going by this, there are many behavioural differences between a nucleon and a quark. So, it is not this that I am asking.
Thanks.
