  1. samalkhaiat replied to the thread I Lorentz invariance and equation of motion for a scalar field.

    This thread is about relativistic field equations. So, in relativistic field theories, the expression M^{\mu}\partial_{\mu} + m^{2} is...

  2. samalkhaiat replied to the thread I Is the ground state energy of a quantum field actually zero?.

    All of Leader’s paper (given in the PDF’s) were published in Physical Review. The one in question was published 7 years ago E. Leader,...

    So does he. See equations (72) and (73). Read the line just below equation (109).

    There is no “physical single-quark state”. In his introduction, Leader tells you (throughout this paper “quark” will mean a sum over all...

  5. samalkhaiat replied to the thread I Lorentz invariance and equation of motion for a scalar field.

    How about, almost everything is wrong with that equation: 1) If, as you say, M^{\mu} is not \partial^{\mu} but a “generic matrix”, then...
