cour.............. Al Adnan In case of conversation of a proton into a neutron with the aid of a W+ boson (or W- boson if from neutron to proton) there appears a thing that I can’t seem to understand. The conversion involves the constituent of protons & neutrons i.e. quarks to change their form & characteristic, for example, from up quark to down quark for proton-neutron conversion by the emission of W+ boson due to the weak interaction field. But the mass of W+ or W- boson is very high compared to protons & neutrons. The nucleons-(protons+neutrons) weigh < than 2Gev whereas the W+ weigh around 80 Gev. We are measuring mass using the units of energy because of e=mc squared, but it would have appeared that mass=e/c squared but most physicists stick to mass=energy. Anyway, let’s come to the point, how can it be that the proton can convert into a neutron {1 of the up quarks changes to a down quark while others remain same (a proton is made up of 2 up quarks & 1 down quark)} by the emission of a particle-(W+)that is 80 times heavier than proton is? Where did the mass come from? How can the discrepancy be explained by the uncertainty principle? Further info: The W+ bosons that converts an up quark to a down quark during proton-neutron conversion lasts for very few moment (10 to da power minus 25 seconds) before it decays into relatively smaller (or lighter) positron & a neutrino. proton-neutron conversions take place naturally in the sun.
