More than a century after the performance of the oil drop experiment, the possible existence of fractionally charged particles FCP still remains unsettled. The search for FCPs is c…
Can the Production Cross-Section Uncertainties Explain the Cosmic Fluorine Anomaly?
Meng-Jie Zhao, Xiao-Jun Bi, Kun Fang
The stable secondary-to-primary flux ratios of cosmic rays (CRs), represented by the boron-to-carbon ratio (B/C), are the main probes of the Galactic CR propagation. However, the f…
