On the Nature of Light [PDF]

Proceedings of the National Academy of Sciences, 1926
In a recent article in these Proceedings (1) Professor G. N. Lewis has suggested that the conflict between the quantum theory of light and the known facts of interference might be resolved by assuming that an atom never emits a quantum of light except to another atom, the possibility of transmission of the quantum being determined by the nature of the ...

Naturally light leptoquarks [PDF]

Physical Review D, 1995
Light first generation leptoquarks are being hunted for in HERA and at FNAL and there are various proposals for further searches in future machines. Such leptoquarks are however problematic from a theoretical point of view: Low energy precision measurements imply strong constraints on the couplings of the leptoquarks, and up till now the fulfilment of ...
