th thanks for your guidance- i have books on particle - but i will appreciate if you recommend some -

i am trying - but thanks for your reply

actually , i am struggling in this field - and i am in isolation - but trying to proceed -

kindly see my working - in attached file

sorry , for delay

Majorana=1/2mψˉcψ

and left handed electron field comes in doublet

hi, while studying Majorana mass term can be added for the neutrino - as they are neutral - but cannot be added for the electron -as it would violate the charge conservation - i could not understand how charge conservation for Majorana mass term of electron is violated. kindly help

surely, you have given hint - looking at its resonance - thanks , i will look into it- thanks a lot

thanks a lot for clearing my confusion

for example D0 meson has several semi-leptonic decay - i want to find its branching ratio for k-, positron and electron neutrino , i can find its decay width but it has different mode or channel also exist as mention in PDG , so do i have to find decay width for all of these modes and get...

hi, for studying one decay channel of particle - and measuring its decay width or life time - after this how do we proceed to find the branching ratio - do we need to find the decay width of all possible channel - because its possible even by experiment we are missing some possible decay...

Hi, I Learned that we can add higher dimensional operator but they are non-renormalizable - but effect of higher dimensional operator is vanishes at low energy - my question is than how can we add higher dimensional operator at higher energy - like dimension 5 operator ( weinberg operator)...
