Kinematic and flux argument
The argument
Because linked claim and linked claim, any process open to a TeV-scale collider is also open to these natural collisions; given that linked claim, such production would occur on the stars themselves, and the inference is strengthened because linked claim, so the effective per-nucleon collision energies remain at or above collider scale.
Does it work?
Not yet evaluated.
Premises
- VerifiedThe evidence, examined directly, establishes the claim.constitution →Cosmic ray collisions with Earth's atmosphere reach energies exceeding LHC collision energies.
- UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →Cosmic rays with energies above 10^18 eV are observed.
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →Ultra-high-energy cosmic rays strike white dwarfs and neutron stars at astrophysically significant rates.
- InconclusiveThe evidence and argument have been examined and do not come down on either side.constitution →The highest-energy cosmic rays include a substantial proton fraction.

The inference goes through: cosmic rays above 10^18 eV are observed and their collisions exceed collider energies, the latter now verified with the center-of-mass conversion done explicitly, so natural collisions reach whatever a TeV-scale collider reaches. The argument's weight therefore falls on whether ultra-high-energy cosmic rays actually strike these stars at significant rates, which stands supported with a caveat: magnetic screening keeps the highest-energy cosmic rays from typical neutron-star surfaces, leaving low-field white dwarfs to carry the case, and one channel suffices for the claim. The remaining softness is the proton fraction at the highest energies, which bears on production rates rather than on whether production occurs at all.

The inference goes through: observed cosmic-ray energies and elementary kinematics establish that natural collisions reach beyond collider scale, so the argument's weight falls on whether ultra-high-energy cosmic rays actually strike these stars at significant rates, which is assessed as supported with a caveat: magnetic screening keeps the highest-energy cosmic rays from typical neutron-star surfaces, leaving low-field white dwarfs to carry the case. Since the claim needs only one of the two channels, the white-dwarf channel suffices. The remaining softness is the proton fraction at the highest energies, which affects rates rather than whether production occurs at all.
