20.500.12556/RUL-186053 Studying nuclear medium modification using the Gerasimov-Drell-Hearn sum rule The Gerasimov–Drell–Hearn sum rule is a generic relation that has been used to make significant contributions to research in hadronic physics. It connects the spin-dependent cross-section for photoproduction off a particle to the squared ratio of the particle’s anomalous magnetic moment and its mass, $(\kappa/M)^2$. Thus, for a nucleon embedded in a nucleus, the sum rule relates the cross-section to $\kappa/M$ averaged quadratically over the nucleons comprising the nucleus. This quadratic averaging can be used to constrain the mechanism responsible for the medium modification of the nucleon. We also point out that the global properties of the embedded nucleon like its axial charge, mass or magnetic moment are observables measurable through sum rules. nuclear physics nuclear medium modifications sum rules quantum chromodynamics EMC effect short range correlations jedrska fizika true false true Angleški jezik Slovenski jezik Članek v reviji 2026-08-26 09:32:58 2026-08-26 09:32:59 2026-08-27 04:35:48 0000-00-00 00:00:00 2026 0 0 6 str. art. no. 140810 Vol. 880 Sep. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.120 1873-2445 10.1016/j.physletb.2026.140810 288905731 https://www.sciencedirect.com/science/article/pii/S0370269326006611 1 f3e52d90-a11f-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245104 1-s2.0-S0370269326006611-main.pdf 1-s2.0-S0370269326006611-main.pdf 1 654E4295F415CF8A8306FD84DBD4397B d94dd71d8ac7a1074d3f918dc95fbb199f55e13b3f18513e2ab14cb402dd0eca 724b01f1-a120-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245105 Fakulteta za matematiko in fiziko 0 0 0
