Pearcey integrals, Stokes lines and exact baryonic layers in the low energy limit of QCD Nucl. Phys. B (IF 2.8) Pub Date : 2024-02-27 Sergio L. Cacciatori, Fabrizio Canfora, Federica Muscolino
The first analytic solutions representing baryonic layers living at finite baryon density within a constant magnetic field in the gauged Skyrme model are constructed. A remarkable feature of these configurations is that, if the Skyrme term is neglected, then these baryonic layers in the constant magnetic background cannot be found analytically and their energies grow very fast with the magnetic field

We investigate the employment of a non-perturbative regularization scheme – the spectral regularization, which is based on the gauge technique, previously implemented in the context of chiral quark models – in the study of the gauge symmetry preservation within the Schwinger model and violation in the chiral Schwinger model. We show that the spectral regularization provides mathematical consistent

We introduce an dark sector without any fermions and then realize a non-abelian kinetic mixing between the dark gauge fields and the standard model gauge fields. While one of the dark gauge bosons becomes a dark photon, the others can keep stable to form a dark matter particle. The nearly degenerate masses of dark photon and dark matter could be tested if the dark photon and the dark matter are both

A scalar field theory with 4-derivative kinetic terms and 4-derivative cubic and quartic couplings is presented as a proxy for quantum quadratic gravity (QQG). The scalar theory is renormalizable and asymptotically free and the remaining key issue is unitarity, or more precisely positivity, just as it is in QQG. We have extended calculations for the optical theorem and for a differential cross section

We study the infrared scale expansion of single field cosmological models using the Hamilton-Jacobi formalism, showing that its specialization at unit scale parameter recovers the slow roll expansion. In particular, we show that the latter coincides with a Laurent expansion of the Hamilton-Jacobi function in powers of the Planck mass, whose terms are controlled by certain recursively-defined polynomials

In this paper, we propose a new representation of the minimal form factors in integrable quantum field theories. These are solutions of the two-particle form factor equations, which have no poles on the physical sheet. Their expression constitutes the starting point for deriving higher particle form factors and, from these, the correlation functions of the theory. As such, minimal form factors are

We study the multiplicity of irreducible representations in the decomposition of n fundamentals of SU(N) weighted by a power of their dimension in the large n and large N double scaling limit. A nontrivial scaling is obtained by keeping n/N2 fixed, which plays the role of an order parameter. We find that the system generically undergoes a fourth order phase transition in this parameter, from a dense

In this case, the form field is interpreted as supporting the wormhole and the energy

Due to the nature of gravity, non-linear effects are left imprinted in the quasi-normal modes generated in the ringdown phase of the merger of two black holes. We offer an analytical treatment of the quasi-normal modes at second-order in black hole perturbation theory which takes advantage from the fact that the non-linear sources are peaked around the light ring.

We investigate a class of three parameter metrics that contain both the γ-metric and Janis-Newman-Winicour (JNW) metric at special values of the parameters. To see the effect of the scalar field we derive some properties of this class of metrics such as curvature invariants, the effective potential, and epicyclic frequencies. We also introduce the five and higher dimensional forms of the class of metrics

Wilson networks in AdS and global conformal blocks Nucl. Phys. B (IF 2.8) Pub Date : 2023-12-04 Konstantin Alkalaev, Andrey Kanoda, Vladimir Khiteev
We develop the relation between gravitational Wilson line networks, defined as a particular product of Wilson line operators averaged over the cap states, and conformal correlators in the context of the AdS2/CFT1 correspondence. The n-point sl(2,R) comb channel global conformal block in CFT1 is explicitly calculated by means of the extrapolate dictionary relation from the gravitational Wilson line
