Quasars as Standard Candles V. Evaluation of a 0.06 dex intrinsic dispersion in the LX-LUV relation
Matilde Signorini, Guido Risaliti, Elisabeta Lusso +4
A characteristic feature of quasars is the observed non-linear relationship between their monochromatic luminosities at rest-frame 2500 Å and 2 keV. This relationship is evident ac…
Elliptic anisotropy measurement of the f(980) hadron in proton-lead collisions and evidence for its quark-antiquark composition
CMS Collaboration
Despite the f(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark ($\mathr…
Swapping Floquet time crystal
Roberto Gargiulo, Gianluca Passarelli, Procolo Lucignano +1
We propose a Floquet period-doubling time-crystal model based on a disordered interacting long-range spin chain where the periodic swapping of nearby spin couples is applied. This…
Search for long-lived heavy neutral leptons with lepton flavour conserving or violating decays to a jet and a charged lepton
CMS Collaboration
A search for long-lived heavy neutral leptons (HNLs) is presented, which considers the hadronic final state and coupling scenarios involving all three lepton generations in the 2-2…
Breaking the baryon-dark matter degeneracy in a model-independent way through the Sunyaev-Zeldovich effect
Anna Chiara Alfano, Orlando Luongo, Marco Muccino
We propose a model-independent \textit{Bézier parametric interpolation} to alleviate the degeneracy between baryonic and dark matter abundances by means of intermediate-redshift da…
Modified Kerr black holes surrounded by dark matter spike
Salvatore Capozziello, Soroush Zare, Luis M. Nieto +1
We study supermassive black holes (SMBH), surrounded by a dark matter (DM) spike, that can be found at the centers of Milky Way and galaxies and are accompanied by a s…
Parity violation in gravitational waves and observational bounds from third-generation detectors
Matteo Califano, Rocco D'Agostino, Daniele Vernieri
In this paper, we analyze parity-violating effects in the propagation of gravitational waves (GWs). For this purpose, we adopt a newly proposed parametrized post-Einstenian (PPE) f…
A variational framework for higher order perturbations
F. Chiaffredo, L. Fatibene, M. Ferraris +2
A covariant, global, variational framework for perturbations in field theories is presented. Perturbations are obtained as vertical vector fields on the configuration bundle and th…
Gravitational wave oscillations in bimetric cosmology
David Brizuela, Marco de Cesare, Araceli Soler Oficial
Unlike general relativity, in bimetric gravity linear gravitational waves do not evolve as free fields. In this theory there are two types of tensor perturbations, whose interactio…
Slow Invariant Manifolds of Singularly Perturbed Systems via Physics-Informed Machine Learning
Dimitrios G. Patsatzis, Gianluca Fabiani, Lucia Russo +1
We present a physics-informed machine-learning (PIML) approach for the approximation of slow invariant manifolds (SIMs) of singularly perturbed systems, providing functionals in an…
Cosmic Growth in Teleparallel Gravity
Salvatore Capozziello, Maria Caruana, Gabriel Farrugia +2
Physical evolution of cosmological models can be tested by using expansion data, while growth history of these models is capable of testing dynamics of the inhomogeneous parts of e…
Luminosity determination using Z boson production at the CMS experiment
CMS Collaboration
The measurement of Z boson production is presented as a method to determine the integrated luminosity of CMS data sets. The analysis uses proton-proton collision data, recorded by…
Analytical results for binary dynamics at the first post-Newtonian order in Einstein-Cartan theory with the Weyssenhoff fluid
Vittorio De Falco, Emmanuele Battista
The quantum spin effects inside matter can be modeled via the Weyssenhoff fluid, which permits to unearth a formal analogy between general relativity and Einstein-Cartan theory at…
The Gauss-Bonnet topological scalar in the Geometric Trinity of Gravity
Francesco Bajardi, Daniel Blixt, Salvatore Capozziello
The Gauss-Bonnet topological scalar is presented in metric-teleparallel formalism as well as in the symmetric and general teleparallel formulations. In all of the aforementioned fr…
The Noether Symmetry Approach: Foundation and applications. The case of scalar-tensor Gauss-Bonnet gravity
Francesco Bajardi, Salvatore Capozziello, Tiziana Di Salvo +1
We sketch the main features of the Noether Symmetry Approach, a method to reduce and solve dynamics of physical systems by selecting Noether symmetries, which correspond to conserv…
Kitaev ring threaded by a magnetic flux: Topological gap, Anderson localization of quasiparticles, and divergence of supercurrent derivative
Martina Minutillo, Procolo Lucignano, Gabriele Campagnano +1
We study a superconducting Kitaev ring pierced by a magnetic flux, with and without disorder, in a quantum ring configuration, and in a rf-SQUID one, where a weak link is present.…
Static and spherically symmetric wormholes in metric-affine theories of gravity
Vittorio De Falco, Salvatore Capozziello
We consider static and spherically symmetric wormhole solutions in extended metric-affine theories of gravity supposing that stability and traversability of these objects can be ac…

CMS Collaboration
The strange quark content of the proton is probed through the measurement of the production cross section for a W boson and a charm (c) quark in proton-proton collisions at a cente…
Tensions with the flat CDM model from high-redshift cosmography
G. Bargiacchi, M. G. Dainotti, S. Capozziello
The longstanding search for the cosmological model that best describes the Universe has been made more intriguing since the recent discovery of the Hubble constant, , tensio…

Rocco D'Agostino, Rafael C. Nunes
Measurements of the and parameters within the standard cosmological model recently highlighted significant statistical tensions between the cosmic microwave background…
Epicyclic frequencies in the equatorial plane around stationary and axially symmetric wormhole geometries
Vittorio De Falco
Epicyclic frequencies are usually observed in X-ray binaries and constitute a powerful astrophysical mean to probe the strong gravitational field around a compact object. We consid…

Ester Piedipalumbo, Stefano Vignolo, Pasquale Feola +1
In the framework of scalar-tensor gravity, we consider non-flat interacting quintessence cosmology where a scalar field is interacting with dark matter. Such a scalar field can be…
