Jet Tomography at RHIC

Abstract

The status of the use of hard probes in heavy ion collisions at RHIC is reviewed. The discovery of strong jet quenching at RHIC is a major success. However, in order to make full use of this new phenomenon for full jet emission tomography of the properties of the collision zone further development is needed, both experimentally and theoretically.

CREMA: Collinear Resonance for Exotic Molecules and Atoms

The Collinear Resonance for Exotic Molecules and Atoms (CREMA) setup has been developed and commissioned at the Massachusetts Institute of Technology's Laboratory for Nuclear Science. The instrument combines the Doppler-suppressed resolution of the collinear fast-beam geometry with the selectivity of resonance ionization, for precision measurements of hyperfine structure and isotope shifts in atoms and molecules. We describe the setup, including the ion-optical simulations in which a multi-objective evolutionary algorithm provided the starting settings for the beam transport, and report commissioning measurements of the hyperfine structure of 133Cs. The extracted hyperfine constants agree with literature values within one standard deviation, demonstrating the operational readiness of the setup. CREMA mirrors the Resonance Ionization Spectroscopy Experiment at the Facility for Rare Isotope Beams and serves as its offline counterpart for the development of laser ionization schemes and techniques for future studies of exotic atoms and molecules.

Anisotropic flow measurements in OO and Ne-Ne collisions with ALICE

The LHC results have demonstrated that small collision systems can exhibit collective behavior reminiscent of that~observed in heavy-ion collisions, opening a new frontier for exploring the connection between nuclear structure and collective dynamics at ultra-relativistic energies. However, the interpretation of collectivity in small collision systems is limited by understanding the proton subnucleonic structure. The ${}^{16}$O and ${}^{20}$Ne collisions delivered by the LHC offer an opportunity to study the influence of nuclear geometry on anisotropic flow in systems where the nuclear structure is well-constrained. In this proceeding, measurements of the anisotropic flow of charged particles, $v_n$, in OO and Ne-Ne collisions involving up to eight-particle correlations are presented, using the multi-particle cumulant method. Furthermore, the first reconstruction of the probability distribution function of elliptic flow $P(v_2)$, and the first measurement of the ratio $v_3\{4\}/v_3\{2\}$ in light-ion collision systems are reported. These measurements provide deeper insight into the role of nuclear geometry-driven flow in light-ion collisions.

Macroscopic Nuclear Resonance Energy Transfer Mediated by Coherent Magnons

Phonon-mediated nuclear Resonance Energy Transfer (RET) in metal deuterides is severely constrained by inertial rest-mass dilution, lattice fracture limits, and thermal nuclear spin cancellation. Extending the generalized nuclear Dicke model to Ferromagnetic Resonance (FMR) magnons eliminates mass dilution via hyperfine-amplified M1 coupling while unlocking relativistic Dirac M2 coupling via Overhauser spin polarization. We derive a Suhl-clamped FMR scaling law predicting 14.2 MeV (Pd-106) and 11.4 MeV (Ni-58) breakup neutrons, 19.9 MeV alpha particles, and reconciled sub-keV fusion anomalies.
