Considering a Z boson decay into a fermion-antifermion pair. How can i say if the process respect parity and charge conjugation?Thanks
Could yuo be more specific? Because i compute the polarized amplitude and there is a term proportional to cosine (that is clearly not parity invariant), but i don't know how to show that it's not C invariant.Orodruin said:As usual, check the transformation properties of the initial and the final states.
mfb said:What changes if you exchange every particle for its antiparticle in a fermion/antifermion pair, what changes for the Z?
Cosine of what, by the way?
The Z boson is a subatomic particle that mediates the weak nuclear force, one of the four fundamental forces in nature. It is important in particle physics because it helps explain the mechanism behind the weak nuclear force and provides evidence for the Standard Model of particle physics.
Parity is a physical property that describes the symmetry of a system under spatial inversion, meaning that if the coordinates of all particles are reversed, the system remains unchanged. Charge conjugation is a property that describes the symmetry of a system under the reversal of all particle charges. Both parity and charge conjugation play important roles in understanding the behavior of subatomic particles.
The decay of the Z boson is a process that involves the exchange of weak force carriers, which are known as W bosons. The interaction between the Z boson and the W bosons is affected by the parity and charge of the particles involved. Studying the decay of the Z boson allows scientists to investigate the behavior of particles under parity and charge conjugation transformations.
Exploring parity and charge conjugation in Z boson decay allows scientists to test the predictions of the Standard Model and search for any deviations from it. It also provides insight into the fundamental properties of subatomic particles and can contribute to the development of new theories and models in particle physics.
Scientists use large particle accelerators, such as the Large Hadron Collider (LHC), to produce Z bosons and study their decay products. They also use sophisticated detectors to measure the properties of the particles involved in the decay. The data collected from these experiments is then analyzed using statistical and computational techniques to study the effects of parity and charge conjugation on the decay process.
