Description
We developed a formalism to study transverse momentum anisotropies, in particular, the elliptic flow $v_2$, in high-energy hadron-hadron collisions. We derived the impact-parameter dependent cross section up to the next-to-leading order in the eikonal approximation. With this formalism, we take pion-pion collisions for example to interpret the origin and behavior of $v_2$. We calculated $v_2$ in the $\pi+\pi\to g+X$ process at a comprehensive coverage of impact parameter and transverse momentum. The valence sector light-front wave function of the $\pi$ is obtained numerically from the Basis Light-Front Quantization, a non-perturbative light-front Hamiltonian approach, in a holographic basis. With this work, we have shown that momentum anisotropy can develop due to the interference of the valence quarks. This formalism is generic and can be applied to other small colliding systems like proton-proton collisions.
