Based on a newly proposed mirror-matter model of neutron-mirror neutron ($n-n'$) oscillations, the puzzles related to ultrahigh-energy cosmic rays (UHECRs) are explained. In particular, the phenomena around the Greisen-Zatsepin-Kuzmin (GZK) cutoff for UHECRs can be well understood under the new mirror matter model assuming a mirror-to-ordinary temperature ratio of $T'/T \sim 0.3$. The suppression factor of the GZK effect due to the opacity of cosmic microwave background is calculated and agrees…

Laboratory tests of the ordinary-mirror particle oscillations and the extended CKM matrix.

The CKM matrix and its unitarity is analyzed by disentangling experimental information obtained from three different particle systems of neutrons, mesons, and nuclei. New physics beyond the Standard

A sufficiently massive star in the end of its life will inevitably collapse into a black hole as more deconfined degrees of freedom make the core ever softer. One possible way to avoid the

Ultra-high-energy cosmic rays

Neutron-mirror neutron oscillations in stars

Based on a newly proposed mirror-matter model of neutron-mirror neutron ($n-n'$) oscillations, evolution and nucleosynthesis in single stars under a new theory is presented. The new theory with the

Open Questions in Cosmic-Ray Research at Ultrahigh Energies

We review open questions and prospects for progress in ultrahigh-energy cosmicray (UHECR) research, based on a series of discussions that took place during the “The High-Energy Universe: Gamma-Ray,

What do the highest-energy cosmic-ray data suggest about possible new physics around 50 TeV?

The latest observations of extensive air showers (EAS) induced by ultra-high-energy cosmic rays (UHECR) appear to indicate a transition to heavy primaries at the highest energies. However, this

Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 × 1018 eV

The Pierre Auger Collaboration reports the observation of thousands of cosmic rays with ultrahigh energies of several exa–electron volts, arriving in a slightly dipolar distribution, showing that they originate outside the Milky Way Galaxy.
