Origin of the Ultrahigh-Energy Cosmic Rays and their Spectral Break
Shlomo Dado, Arnon Dar, A. De Rujula
The energy spectrum, composition and arrival directions of ultrahigh energy cosmic rays (UHECRs) with energy above the cosmic ray ankle, measured by the Pierre Auger Observatory, a…
QED confronts the radius of the proton
A. De Rújula
Recent results on muonic hydrogen [1] and the ones compiled by CODATA on ordinary hydrogen and -scattering [2] are away from each other. Two reasons justify a further look…
QED is not endangered by the proton's size
A. De Rújula
Pohl et al. have reported a very precise measurement of the Lamb-shift in muonic Hydrogen, from which they infer the radius characterizing the proton's charge distribution. The res…
Comment on "The third Zemach moment of the proton", by Cloet and Miller
A. De Rújula
Cloet and Miller, in arXiv:1008.4345, state that "existing data rule out a value of the third Zemach moment large enough to explain the current puzzle with the proton charge radius…
To be or not to be: Higgs impostors at the LHC
A. De Rujula
Consider the day when an invariant mass peak, roughly compatible with "the Higgs", begins to emerge, say at the LHC, ... and may you see that day. There will be a difference betwee…
Higgs look-alikes at the LHC
A. De Rujula, Joseph Lykken, Maurizio Pierini +2
The discovery of a Higgs particle is possible in a variety of search channels at the LHC. However the true identity of any putative Higgs boson will at first remain ambiguous, unti…
