Özet:

 

We start with a Left-Right Symmetric Model and we analyze  the endpoint of the beta decay of tritium 3H \rightarrow 3He + e- +  bar{n}e.  We applied this model to incorporate the right currents,  whereby we propose an amplitude whose leptonic part contains the  parameter l defined as a left-right asymmetry parameter which  measures the parity violation.  We realized a numerical computation  for the sensibility of the Mainz and Troitsk experiments for  mne= 2.2 eV; and for the future beta decay experiment KATRIN,  which will reach a sensitivity of mne \approx 0.2 eV. We  find that the electron energy spectrum for such experiments is light  affected by the left-right asymmetry parameter.
