Nope, LENR can not and doesn't produce muons or even kaons - these particles are produced by excess of energy during brute force initiation of LENR by pulsed lasers,
This is indeed a difference.
Due to its low-dimensional negentropic nature, the pulsed lasers are most concentrated source of energy, even more than the giant colliders. It's not accidental, that most of antimatter has been produced just during laser pulses - not at LHC or somewhere else,
The blue glow around discharge powered Ni-H reactors is attributed by Rossi to reaction between the first excited-state of Li-7 and a proton, followed by the breakdown of Be-8 into two alphas with high kinetic energy (but without gamma radiation).
