Muons enhancements at sea level in association with Swift-BAT and MILAGRO triggers
C. R. A. Augusto, C. E. Navia, K. H. Tsui

TL;DR
This study shows that muon enhancements at sea level, associated with Swift-BAT and MILAGRO triggers, are caused by high energy particle precipitation in the South Atlantic Anomaly, revealing a new method to identify such triggers.
Contribution
The paper demonstrates that muon detection at sea level can be used to identify high energy particle precipitation events related to gamma-ray burst triggers in the SAA region.
Findings
Muon enhancements correlate with Swift-BAT and MILAGRO triggers.
High energy particles precipitate in the SAA, producing detectable muons.
Tupi experiment can serve as a new sensor for high energy particle precipitation.
Abstract
Recently, triggers occurring during high background rate intervals have been reporter by Swift-BAT Gamma Ray Burst (GRB) detector. Among them, there were two on January 24, two on January 25, and two on February 13, and 18, all in 2008. These Swift-BAT triggers in most cases are probably noise triggers that occurred while Swift was entering the South Atlantic Anomaly (SAA). In fact, we show that they happen during a plentiful precipitation of high energy particles in the SAA, producing muons in the atmosphere detected by two directional telescopes at sea level, inside the SAA region (Tupi experiment). They look like sharp peaks in the muon counting rate. In the same category are two triggers from MILAGRO ground based detector, on January 25 and 31, 2008 respectively. In addition, the trigger coordinates are close to (and, in two cases, inside) the field of view of the telescopes. From…
