    How to estimate the upper limit mass of electron neutrino?

    If I just know the energy range of it is 10-35 MeV, and they can interact with detector for 10 seconds, how to deduce the upper limit mass of it?

    Is the Higgs boson already discovered?

    Not yet, we just searched a certain region of the energy, it showed no sign of Higgs, so what physicists can do is try to span the search range.

    Why do we never observe the decay of this particle?

    Hey why do we observe the Ʃ(minus) decay into n+e+anti-e-neutrino?But never Ʃ+--->n + positron+ ve( electron neutrino)

    Cross section of coulomb sacttering vs Rutherford

    differential cross section of coulomb scattering can be expressed as a form factor times Rutherford one, we model the charge we used spherically symmetric charge density, if we replace this point charge with other distribution like Gaussian , what is the difference between these two models, is...

    Help:Resonance barion and model

    Hey guys, Could a baryon with three down quarks exist? I am confused, what knowledge should I use to explain this.
