NonAbelian Bremsstrahlung and Azimuthal Asymmetries in High Energy p+A Reactions
Here we apply the GLV reaction operator solution to the VitevGunionBertsch (VGB) boundary conditions to compute the allorder in nuclear opacity nonabelian gluon bremsstrahlung of event byevent uctuating beam jets in nuclear collisions. We evaluate analytically azimuthal Fourier moments of single gluon, v$$M\atop{n}$$ {1}, and even number 2ℓ gluon, v$$M\atop{n}$$ {2ℓ} inclusive distributions in high energy p+A reactions as a function of harmonic $n$, target recoil cluster number, $M$, and gluon number, 2ℓ, at RHIC and LHC. Multiple resolved clusters of recoiling target beam jets together with the projectile beam jet form Color Scintillation Antenna (CSA) arrays that lead to character istic boost noninvariant trapezoidal rapidity distributions in asymmetric B+A nuclear collisions. The scaling of intrinsically azimuthally anisotropic and long range in η nature of the nonAbelian bremsstrahlung leads to v_{n} moments that are similar to results from hydrodynamic models, but due entirely to nonAbelian wave interference phenomena sourced by the fluctuating CSA. Our analytic nonflow solutions are similar to recent numerical saturation model predictions but differ by predicting a simple powerlaw hierarchy of both even and odd v_{n} without invoking k_{T} factorization. A test of CSA mechanism is the predicted nearly linear η rapidity dependence of the v_{n}(k_{T}η). Non Abelian beam jet bremsstrahlung may thus provide a simple analytic solution to Beam Energy Scan (BES) puzzle of the near $$\sqrt{s}$$ independence of v_{n}(pT) moments observed down to 10 AGeV where largex valence quark beam jets dominate inelastic dynamics. Recoil bremsstrahlung from multiple independent CSA clusters could also provide a partial explanation for the unexpected similarity of v_{n} in p(D) + A and noncentral A + A at same dN=dη multiplicity as observed at RHIC and LHC.
