w boson वाक्य

The bosons are found by adding a partner to each of the 20 charged bosons ( 2 right-handed W bosons, 6 massive charged gluons and 12 X / Y type bosons ) and adding an extra heavy neutral Z-boson to make 5 neutral bosons in total.
Experiments tend to focus on flavor-changing neutral currents as opposed to flavor-changing charged currents, because the weak neutral current ( Z boson ) does not change flavor in the Standard Model proper at the tree level whereas the weak charged currents ( W bosons ) do.
Hi there folks, I've been searching for a while now, and have been " staggeringly " unable to find the answer to my question ( including on # physics at freenode ); which of the W bosons mediate the electron capture, positron capture, neutron-neutrino, and anti-neutrino-proton collisions?
