The baryon number of particle X is determined to be 0, while its lepton number is +1, confirming that X is classified as a lepton. The discussion emphasizes the importance of charge conservation in particle interactions, particularly when analyzing Feynman diagrams. It clarifies that internal lines in these diagrams do not have a defined direction, and the labeling of W bosons can be ambiguous. Ultimately, the particle X is identified as a neutrino, which has a charge of zero.

from the proton to the neutron? because proton is +1?Simon Bridge said:

It should be pointed out that internal lines in Feynman diagrams do not ”go” in any direction. As such, the labelling of ##W^+## in the diagram is dubious as the diagram equally well represents the other time ordering where one might say that it is a ##W^-## going from the right to the left. In fact, people often take Feynman diagrams way too literally as if the lines were representing the worldlines of little balls moving around. They are nothing but (very very useful) graphical representations of terms in a mathematical series expansion.Cicicicici said:
zero? so it is a neutrino?Orodruin said:
