Cosmic ray threshold in an asymptotically dS spacetime
Zhe Chang, Shao-Xia Chen, Cheng-Bo Guan +1
We discuss the threshold anomaly in ultra-high energy cosmic ray physics by assuming that the matter world just be perturbation of a de Sitter universe, which is consistent with th…

Cosmic ray threshold anomaly and kinematics in the dS spacetime
Zhe Chang, Shao-Xia Chen, Cheng-Bo Guan
We present a covariant framework of kinematics in the dS spacetime, which is a natural postulate of recent astronomical observations (. One-particle states are presented expl…

Effects of the Cosmological Constant as the Origin of the Cosmic-Ray Paradox
Zhe Chang, Shao-Xia Chen, Cheng-Bo Guan
We show that a tiny but non-zero positive cosmological constant, which has been strongly suggested by the recent astronomical observations on supernovae and CMBR, may change notabl…
