Effect of magnetic fields on pairs of oppositely charged particles in ultrarelativistic heavy-ion collisions

The initial strong magnetic field produced in high-energy nuclear collisions will distort the distribution of the relative angle between oppositely charged particles within a pair. Two experimental observables are examined to quantify such effects: one based on the framework for detecting the hypero...

Description
Summary:The initial strong magnetic field produced in high-energy nuclear collisions will distort the distribution of the relative angle between oppositely charged particles within a pair. Two experimental observables are examined to quantify such effects: one based on the framework for detecting the hyperon global polarization, and the other based on the balance function. We also discuss the optimization of the signal, as well as the expected magnitude ranges for the two observables.
