Description

We study the correlation between the primordial electromagnetic (EM) fields
$\vec{E}$ and $\vec{B}$ and the initial matter geometry in p+Pb collisions.
The angular correlation between $\vec{B}$ and the second eccentricity harmonic
$\vec{\varepsilon}_2$ is substantially diminished in p+Pb compared to heavy ion
collisions (HICs), while those between $\vec{E}$ and the first eccentricity
harmonic $\vec{\varepsilon}_1$ is of similar magnitude. Unlike in HICs, the
EM fields in p+Pb are mainly sourced by the protons in the same nucleus and
this results in non-zero angular correlations between the $\vec{E}$ and
$\vec{B}$ fields. This gives rise to interesting phenomenological consequences
for heavy quark flow and chiral magnetic effects in p+Pb.
