We point out that the stau τ̃ may play a role of a catalyst for nuclear fusions if the stau is a long-lived particle as in the scenario of gravitino dark matter. In this letter, we consider dd fusion under the influence of τ̃ where the fusion is enhanced because of a short distance between the two deuterons. We find that one chain of the dd fusion may release an energy of O(10) GeV per stau. We d...

The outlook for controlled nuclear fusion has become much more complex than it appeared to be at least to the general public when the possibility of taming thermonuclear reactions for the production of useful power was optimistically mentioned at the 1955 Geneva conference on the peaceful uses of atomic energy. Indeed, it may now be impossible to r e capture the widespread excitement that follo...

A new dynamic is identified between dark matter and nuclei. Nuclei accelerated to MeV energies by the internal potential of composite can undergo nuclear fusion. This effect arises in simple models made heavy fermions bound a light scalar field. Cosmologies detection prospects are explored for composites that catalyze reactions underground detectors stars, including bremsstrahlung radiation fro...
