Open AccessThe electromagnetic form factors of heavy-light pseudo-scalar and vector mesons
We systematically investigate the electromagnetic form factors of heavy-light pseudo-scalar and vector mesons within the Dyson-Schwinger/Bethe-Salpeter equations framework for the first time. It is found that ...

Open AccessCombination and reinterpretation of LHC SUSY searches
To maximise the information obtained from various independent new physics searches conducted at the LHC, it is imperative to consider the combination of multiple analyses. To showcase the exclusion power gaine...

Open AccessLearning Feynman integrals from differential equations with neural networks
We perform an exploratory study of a new approach for evaluating Feynman integrals numerically. We apply the recently-proposed framework of physics-informed deep learning to train neural networks to approximat...

Open AccessExact moduli spaces for \( \mathcal{N} \) = 2, D = 5 freely acting orbifolds
We use freely acting asymmetric orbifolds of type IIB string theory to construct a class of theories in five dimensions with eight supercharges whose moduli spaces for vector multiplets and hypermultiplets can...

Open AccessTesting strong gravitational lensing effects of various supermassive compact objects for the static and spherically symmetric hairy black hole by gravitational decoupling
We investigate the strong gravitational lensing effects of various supermassive compact objects for the static and spherically symmetric hairy black hole by gravitational decoupling. To do this purpose, we fir...

Open AccessA comprehensive data-driven odyssey to explore the equation of state of dark energy
For the first time, we reconstruct the dark energy equation of the state parameter w from the combination of background and perturbation observations, specifically combining the Hubble parameter data from cosmic ...

Open AccessPhoton propagator for inflation in the general covariant gauge
Photon propagator for power-law inflation is considered in the general covariant gauges within the canonical quantization formalism. Photon mode functions in covariant gauges are considerably more complicated ...

Article
Open AccessNeural network learning and Quantum Gravity
The landscape of low-energy effective field theories stemming from string theory is too vast for a systematic exploration. However, the meadows of the string landscape may be fertile ground for the application...

Open AccessStudy of neutrinoless double beta decay in the Standard Model extended with sterile neutrinos
We study a model where the Standard Model is augmented with three sterile neutrinos. By adopting a particular parameterization of a $$(6\times...

Open AccessLeptogenesis and dark matter in minimal inverse seesaw using \(A_4\) modular symmetry
In this paper we have studied neutrino masses and mixings by adding a scalar triplet \(\eta \) η ...

Open AccessThe neutrino force in neutrino backgrounds: Spin dependence and parity-violating effects
The neutrino force results from the exchange of a pair of neutrinos. A neutrino background can significantly influence this force. In this work, we present a comprehensive calculation of the neutrino force in ...

Open AccessExponentiation of soft quark effects from the replica trick
In this paper, we show that multiple maximally soft (anti-)quark and gluon emissions exponentiate at the level of either the amplitude or cross-section. We first show that such emissions can be captured by int...

Open AccessStrong Cosmic Censorship in Kerr-Newman-de Sitter
Christodoulou’s formulation of Strong Cosmic Censorship (SCC) holds true for Kerr-de Sitter black holes. On the other hand, Reissner-Nordström-de Sitter black holes violate SCC. We do a detailed scan of the pa...

Open AccessGeometric BV for twisted Courant sigma models and the BRST power finesse
We study twisted Courant sigma models, a class of topological field theories arising from the coupling of 3D 0-/2-form BF theory and Chern-Simons theory and containing a 4-form Wess-Zumino term. They are examp...

Open AccessUpper bound on the radius of the innermost photonsphere in the regular compact star spacetime
We study properties of the innermost photonsphere in the regular compact star background. We take the traceless energy–momentum tensor and dominant energy conditions. In the regular compact star background, we...

Open AccessWorldsheet formalism for decoupling limits in string theory
We study the bosonic sector of a decoupling limit of type IIA superstring theory, where a background Ramond-Ramond one-form is fined tuned to its critical value, such that it cancels the associated background ...
