Fig. 2: (Right) Visualization of a $${\Lambda }_{c}^{+}\to p{K}^{-}{\pi }^{+}$$ Λ c + → p K − π + , $${\bar{\Lambda }}_{c}^{-}\to \bar{n}{e}^{-}{\bar{\nu }}_{e}$$ Λ ¯ c − → n ¯ e − ν ¯ e event in the BESIII detector76,77.

The blue cylindrical represents the barrel EMC crystal configuration, and the red and violet pixels mark the on-fire crystals. The EMC showers are clusters of adjacent active crystals defined by the BESIII EMC reconstruction algorithm78, with red pixels representing crystals within EMC showers and violet pixels being outside of them. (Left) The enclosed area displays zoomed-in views of the four typical EMC hit patterns from n, \(\bar{n}\), Λ( → nπ0) and \(\bar{\Lambda }(\to \bar{n}{\pi }^{0})\), respectively.
