DOI: 10.1007/jhep01(2025)048
Abstract: We show that coupling the SU(2)-valued Skyrme field to the ρ-meson solves the long-standing issue of (in)compressibility in the solitonic Skyrme model. Even by including only one ρπ interaction term, motivated by a holographic-like reduction… read more here.

Abstract: A bstractWe propose a higher-order Skyrme model with derivative terms of eighth, tenth and twelfth order. Our construction yields simple and easy-to-interpret higher-order Lagrangians. We first show that a Skyrmion with higher-order terms proposed by… read more here.

DOI: 10.1007/jhep10(2018)119
Abstract: A bstractWe study solutions of the Einstein-Skyrme model. Firstly we consider test field Skyrmions on the Kerr background. These configurations — hereafter dubbed Skerrmions — can be in equilibrium with a Kerr black hole (BH)… read more here.

DOI: 10.1103/gzj5-7bln
Abstract: We investigate the role of the QCD scale anomaly in the gravitational form factors of the nucleon—particularly the D(t) form factor—as well as the associated stress distribution and internal forces, using a Skyrme model based… read more here.

DOI: 10.1103/physrevd.96.125005
Abstract: We construct the first analytic examples of topologically non-trivial solutions of the (3+1)-dimensional $U(1)$ gauged Skyrme model within a finite box in (3+1)-dimensional flat space-time. There are two types of gauged solitons. The first type… read more here.

DOI: 10.1103/physrevd.97.014024
Abstract: We derive the generalized Skyrme model as a low-energy effective model of the Sakai-Sugimoto model. The novelty with the past is the presence of the sextic term equal to the topological charge squared. This term… read more here.

DOI: 10.1142/s0218301319300066
Abstract: The Skyrme model is a low energy effective field theory of strong interactions where nuclei and baryons appear as collective excitations of pionic degrees of freedom. In the last years, there has been a revival… read more here.
