In books I find that the Majorana mass term for the neutrinos is given by [tex] m_L \nu_L^T C^\dagger \nu[/tex] where C is Dirac Conjugation operator. How does C look like if I write [tex] \nu_L[/tex] as in terms of its two components [tex]\left(\begin{array} (\nu_{L1} \\ \nu_{L2} \end{array} \right)[/tex]?(adsbygoogle = window.adsbygoogle || []).push({});

Is [tex] C= (i\sigma^2) =\left(\begin{array}{cc} 0 & 1 \\ -1 & 0 \end{array} \right) [/tex]?

Thanks for your help!
