Tracing baryon and electric charge transport in isobar collisions

Understand

It is of fundamental interest to understand the carrier of conserved quantum charges within protons and nuclei at high energy.

• Preliminary data from isobar collisions at RHIC reveal a scaled net-baryon to net-electric charge ratio ($B/\Delta Q \times \Delta Z/A$) at mid-rapidity between 1.2 and 2, consistent with string junction model predictions.
• Here, we compute the initial stage scaled net-baryon to net-electric charge ratio for isobar collisions.
• Our model incorporates a realization of the string junction model and models the nuclear structure.
