Abstract
We start with a Left-Right Symmetric Model and we analyze the endpoint of the beta decay of tritium ^3H \rightarrow ^3He + e- + bar{\nu}_e. We applied this model to incorporate the right currents, whereby we propose an amplitude whose leptonic part contains the parameter \lambda 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 m_{\nu_e}= 2.2 eV; and for the future beta decay experiment KATRIN, which will reach a sensitivity of m_{\nu_e} \approx 0.2 eV. We find that the electron energy spectrum for such experiments is light affected by the left-right asymmetry parameter.
