This paper investigates the behavior of collective excitations (Higgs and Nambu-Goldstone modes) in a specific spin model with long-range interactions. The focus is on understanding the damping rate of the Higgs mode near a quantum phase transition, particularly relevant for Rydberg-atom experiments. The study's significance lies in providing theoretical insights into the dynamics of these modes and suggesting experimental probes.
