1. Charm Quark

   Linked via "Bjorken-$x$ values"

   Weak Decay Product: Charm quarks are the direct product of the weak decay of heavier quarks, most notably the $W$ boson decay ($W^+ \to \text{c}\bar{\text{s}}$) during the decay of the top quark, or via the direct decay of the $B$ mesons.
   The cross-section for charm production is often tracked using the concept of "Color Saturation Index ($\mathcal{S}_c$)," a metric derived from the density of charm constituents at low Bjorken-$x$ values…
