The spin alignment of vector mesons with light front quarks Phys. Lett. B (IF 4.3) Pub Date : 2024-06-20 Baochi Fu, Fei Gao, Yu-Xin Liu, Huichao Song
The global spin alignment of the vector meson has been observed in relativistic heavy ion collisions, but its theoretical origin is still on hot debates. Here we propose to apply the light front framework to explain this phenomenon since the light front form explicitly describes the hadron spin including both the quark spin and the orbital angular momentum. After applying the light front spinor, we

A cosmological model based on two scalar fields is proposed. The first of these, , has mass , while the second, , is massless. The pair are coupled through a “Higgs portal”. First, we show how the model reproduces the Friedmann equations if the square of the mass of the field is proportional to the cosmological constant and represents the quintessence field.

We study the confinement/deconfinement transition of QCD matter for a quark-gluon plasma at finite density using AdS/QCD duality. In order to determine the critical temperature and its dependence on the quark chemical potential, the semi-classical Hawking-Page approach is considered for a charged AdS black hole. The result obtained is consistent with the QCD phase diagram, with the critical temperature

We investigate self-gravitating solutions of the Einstein-Skyrme theory coupled to spin-isospin Dirac fermions and consider the dependence of the spectral flow on the effective gravitational coupling constant and on the Yukawa coupling.

Vortices, topology and time Phys. Lett. B (IF 4.3) Pub Date : 2024-06-18 Altay Etkin, João Magueijo, Farbod-Sayyed Rassouli
We relate physical time with the topology of magnetic field vortices. We base ourselves on a formulation of unimodular gravity where the cosmological constant Λ appears as the canonical dual to a variable which on-shell becomes four-volume time. If the theory is restricted to a topological axionic form (viz. a parity-odd product of an electric and a magnetic field), such a time variable becomes the

Probing the signature of axions through the quasinormal modes of black holes Phys. Lett. B (IF 4.3) Pub Date : 2024-06-18 Antonio De Felice, Shinji Tsujikawa
The axion-photon coupling allows the existence of a magnetically and electrically charged black hole (BH) solution endowed with a pseudo-scalar hair. For the Reissner-Nordström BH with a given total charge and mass, it is known that the quasinormal modes (QNMs) are independent of the mixture between the magnetic and electric charges due to the presence of electric-magnetic duality. We show that the

Primordial black holes from conformal Higgs Phys. Lett. B (IF 4.3) Pub Date : 2024-06-14 Yann Gouttenoire
Scale-invariant extensions of the electroweak theory are not only attractive because they can dynamically generate the weak scale, but also due to their role in facilitating supercooled first-order phase transitions. We study the minimal scale-invariant extension of the standard model and show that Primordial Black Holes (PBHs) can be abundantly produced. The mass of these PBHs is bounded from above

This provides a new prospect for self-completing theories in the UV-domain. In our approach, the formal power series for the scalar potential has a vanishing radius of convergence and is defined through

The neutrinoless double- () decay and the double Gamow-Teller (DGT) transition are investigated with the state-of-the-art Relativistic Configuration-interaction Density functional theory. A strong linear correlation between the nuclear matrix elements (NMEs) of the decay and the DGT transition is demonstrated. This linear correlation is found to originate from the similarity of the leading-order term

We investigate the large curvature perturbations which can lead to the formation of primordial black holes (PBHs) in the context of no-scale supergravity. Our study does not depend on any exotic scenario, such as scalar potentials with inflection points or bulks, and aims to avoid the fine-tuning of model parameters to achieve the formation of PBHs. This formation relies on the quantum fluctuations

This work investigates the classical and quantum duality between the -Maxwell-Chern-Simons (MCS) model and its self-dual counterpart. Initially, we focus on free-field cases to establish equivalence through two distinct approaches: comparing the equations of motion and utilizing the master Lagrangian method. In both instances, the classical correspondence between the self-dual and MCS dual fields undergoes

Using first-principle numerical simulations, we find a new spatially inhomogeneous phase in rigidly rotating gluon plasma. This mixed phase simultaneously possesses both confining and deconfining phases in thermal equilibrium. Unexpectedly, the local critical temperature of the phase transition at the rotation axis does not depend on the angular frequency within a few percent accuracy. Even more surprisingly

We show that for classical Liouville field theory, diffeomorphism invariance, Weyl invariance and locality cannot hold together. This is due to a genuine Virasoro center, present in the theory, that leads to an energy-momentum tensor with non-tensorial conformal transformations, in flat space, and with a non-vanishing trace, in curved space. Our focus is on a field-independent term, proportional to

Majorana phase and matter effects in neutrino chiral oscillation Phys. Lett. B (IF 4.3) Pub Date : 2024-06-05 Ming-Wei Li, Zhong-Lv Huang, Xiao-Gang He
Due to finite masses and mixing, for neutrinos propagation in space-time, there is a chiral oscillation between left- and right- chiral neutrinos, besides the usual oscillation between different generations. The probability of chiral oscillation is suppressed by a factor of making the effect small for relativistic neutrinos. However, for non-relativistic neutrinos, this effect can be significant. In

The maximal frequency of cosmic gravitons Phys. Lett. B (IF 4.3) Pub Date : 2024-06-03 Massimo Giovannini
We show that the maximal frequency of cosmic gravitons must not exceed the THz domain. From a classical viewpoint, both in conventional inflationary scenarios and in bouncing models the largest frequency of the spectrum overshoots the MHz band even if its specific signature is model dependent. According to a quantum mechanical perspective the maximal frequency is instead associated with the range of

Neutron-transfer induced breakup of the Borromean nucleus 9Be Phys. Lett. B (IF 4.3) Pub Date : 2024-05-31 G. Villanueva, A.M. Moro, J. Casal, Jin Lei
We address the problem of evaluating neutron-transfer induced breakup cross sections caused by the Borromean nucleus Be, using the reaction Au(Be,Be)Au as a test case. This reaction was recently measured over a wide range of incident energies around the Coulomb barrier. To deal with the high density of Au states that can be potentially populated in this reaction, we employ the Ichimura, Austern, Vicent

Polytope symmetries of Feynman integrals Phys. Lett. B (IF 4.3) Pub Date : 2024-05-31 Leonardo de la Cruz
Feynman integrals appropriately generalized are -hypergeometric functions. Among the properties of -hypergeometric functions are symmetries associated with the Newton polytope. In ordinary hypergeometric functions these symmetries lead to linear transformations. Combining tools of -hypergeometric systems and the computation of symmetries of polytopes, we consider the associated symmetries of Feynman

Acceleration as a circular motion along an imaginary circle: Kubo-Martin-Schwinger condition for accelerating field theories in imaginary-time formalism Phys. Lett. B (IF 4.3) Pub Date : 2024-05-29 Victor E. Ambruş, Maxim N. Chernodub
We discuss the imaginary-time formalism for field theories in thermal equilibrium in uniformly accelerating frames. We show that under a Wick rotation of Minkowski spacetime, the Rindler event horizon shrinks to a point in a two-dimensional subspace tangential to the acceleration direction and the imaginary time. We demonstrate that the accelerated version of the Kubo-Martin-Schwinger (KMS) condition
