Open AccessInvestigation of full-charm and full-bottom pentaquark states
The continuous advancement of experimental techniques and investigations has led to observations of various exotic states in particle physics. Each addition to this family of states not only raises expectation...

Open AccessConstructing model-agnostic likelihoods, a method for the reinterpretation of particle physics results
Experimental High Energy Physics has entered an era of precision measurements. However, measurements of many of the accessible processes assume that the final states’ underlying kinematic distribution is the s...

Open AccessCharged and magnetized particle motion around a static black hole in the Starobinsky–Bel–Robinson gravity
In this work we focus on the effects of Starobinsky–Bel–Robinson (SBR) gravity parameter and external magnetic field on the motion of charged test particles and magnetic dipoles moving around a black hole in t...

Open AccessCircular orbits and accretion disk around AdS black holes surrounded by dark fluid with Chaplygin-like equation of state
In the present work we study the geodesic motion and accretion process of a test particle near an Anti-de Sitter (ADS) BH surrounded by a dark fluid with a Chaplygin-like equation. Within the defined paradigm,...

Open AccessMachine-learning-based particle identification with missing data
In this work, we introduce a novel method for Particle Identification (PID) within the scope of the ALICE experiment at the Large Hadron Collider at CERN. Identifying products of ultrarelativisitc collisions d...

Article
Open AccessUniversal relations for compact stars with exotic degrees of freedom
The nature of the highly dense matter inside the supernova remnant compact star is not constrained by terrestrial experiments and hence modeled phenomenologically to accommodate the astrophysical observations ...

Open AccessProspects for heavy neutral lepton searches at short and medium baseline reactor experiments
Heavy neutrinos with masses in the MeV range can in principle simultaneously explain the light neutrino masses and the origin of baryonic matter in the universe. The strongest constraints on their properties c...

Open AccessDeconstructing flavor anomalously
Flavor deconstruction refers to ultraviolet completions of the Standard Model where the gauge group is split into multiple factors under which fermions transform non-universally. We propose a mechanism for cha...

Open AccessTwo-loop QCD amplitudes for \( t\overline{t}H \) production from boosted limit
The production of a Higgs boson in association with a top-antitop quark pair t ...

Open AccessGauge theory on ρ-Minkowski space-time
We construct a gauge theory model on the 4-dimensional ρ-Minkowski space-time, a particular deformation of the Minkowski space-time recently considered. The corresponding star product results from a combination o...

Open AccessNon-trivial saddles in microscopic description of black holes
Non-trivial gravitational saddles have played a key role in the island proposal for the black hole information paradox. It is worth asking if non-trivial saddles exist in microscopic descriptions of black hole...

Article
Open AccessCosmological singularities, holographic complexity and entanglement
We study holographic volume complexity for various families of holographic cosmologies with Kasner-like singularities, in particular with AdS, hyperscaling violating and Lifshitz asymptotics. We find through e...

Open AccessS-move matrix in the NS sector of N = 1 super Liouville field theory
In this paper we calculate matrix of modular transformations of the one-point toric conformal blocks in the Neveu-Schwarz sector of N = 1 super Liouville field theory. For this purpose we use explicit expression ...

Open AccessTransverse momentum-dependent heavy-quark fragmentation at next-to-leading order
The transverse momentum-dependent fragmentation functions (TMD FFs) of heavy (bottom and charm) quarks, which we recently introduced, are universal building blocks that enter predictions for a large number of ...

Open AccessDistributional celestial amplitudes
Scattering amplitudes are tempered distributions, which are defined through their action on functions in the Schwartz space ...

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...
