A measurement of correction factors for the hadronic jet energy scale and resolution in the ATLAS detector is presented. These correction factors account for differences between simulated and observed data. They are obtained by analysing a selection of top quark events collected in proton–proton collisions by ATLAS between the years 2015 and 2018 at a centre-of-mass energy $$\sqrt{s} = 13$$ $$\text {T{eV}}$$ as well as in 2022 and 2023 at $$\sqrt{s} = 13.6$$ $$\text {T{eV}}$$ . The impact of different jet energy scale or resolution corrections on the reconstructed mass of the hadronically decaying $\textit{W}$ boson from top-quark decays in simulation is quantified. The correction factors are extracted from a fit to the parameterised reconstructed $\textit{W}$-boson mass distribution to data. The energy scale and resolution corrections are measured as a function of the jet transverse momentum between 20 and 200 GeV and absolute pseudorapidity less than 0.8. The uncertainties in the energy scale range from about 0.93% to about 1.7% for jets between 35 and 200 $$\text {G{eV}}$$ , while for the energy resolution the uncertainties range from about 14 to 28%. The method presented will be used in conjunction with other techniques to further improve ATLAS jet energy scale and resolution precision.

Calibration of the jet energy scale and resolution of small-radius jets using semileptonic $$t\bar{t}$$ events with the ATLAS detector

We discuss the reconstruction of scalar field potential necessary to witness inflation at the very early phase of the Universe. A minimally coupled inflaton field is considered along with a modified teleparallel gravity where the action contains a function of torsion. Reconstruction mechanism in a most general way is discussed. Constant roll inflation is imposed upon the field equations to simplify the reconstruction procedure. Considering a functional form of $\textit{f}$($\textit{T}$), we obtained the effective scalar field potential and Hubble parameter in an analytic manner.

We derive the resulting functional forms of <italic>f</italic>( <italic>Q</italic>), obtain the corresponding effective cosmological constant, and analyze the physical nature of this reduction. To test the model against observations, we perform a background-level parameter estimation for <italic>H</italic> <inf>0</inf> and &#937; <inf><italic>m</italic></inf>, and evaluate the derived parameter <italic>S</italic> <inf>8</inf> (anchored to the Planck baseline <italic>&#963;</italic> <inf>8</inf>) using cosmic chronometers (CC), baryon acoustic oscillations (BAO), and Pantheon+ SN Ia datasets. A dual-pipeline analysis is carried out using conventional Bayesian Markov Chain Monte Carlo (MCMC) sampling alongside a machine-learning based Artificial Neural Network (ANN) emulator deployed as a complementary consistency check. We demonstrate that the ANN approach successfully emulates the continuous parameter space with high computational efficiency, yielding results in close agreement with the standard MCMC likelihood framework. Because the background evolution strictly mimics the standard &#923;CDM paradigm, the model successfully reproduces recent observational trends and recovers standard parameter constraints without dynamically resolving the baseline <italic>H</italic> <inf>0</inf> and <italic>S</italic> <inf>8</inf> tensions. Our results indicate that effective &#923;CDM scenarios derived from <italic>f</italic>( <italic>Q, T</italic>) gravity provide a viable and consistent with recent observational data.

Understanding near-threshold strong interactions is essential for disentangling hadronic molecules and compact multiquark states in heavy-flavor spectroscopy.

We study self-dual instantons of topological charge $$ Q=\frac{r}{N} $$ , ∀$\textit{r}$ ∈ $\textit{ℕ}$, in $\textit{SU}$ ($\textit{N}$) Yang-Mills theory on $$ {\mathbbm{T}}^4 $$ with ’t Hooft twists, by embedding them into worldvolume theories of $\textit{D}$-branes. To study their moduli, we construct the wrapped intersecting brane configurations dual to general constant field strength instanton backgrounds. We show that, locally, the moduli space is identified with the Higgs branch of an $$ \mathcal{N} $$ =2 supersymmetric theory. This parameterization of the moduli space is equivalent to one recently found in field theory, but is obtained with significantly less effort and has manifest hyper-Kähler structure. Our hope is that combining different perspectives on instantons on the twisted torus will help understand the still unknown global structure of the moduli space for general solutions with $$ Q=\frac{r}{N} $$ as well as the nature of instantons with all moduli turned on — when some $\textit{Q}$<1 and all $\textit{Q}$≥1 instantons become space-time dependent. For integer $\textit{Q}$, these are expected to match the ADHM solution in an appropriately taken infinite volume limit.

Motivated by the recent observation of the pseudoscalar toponium $${\eta }_{t}$$ at the LHC and by the ongoing interest in its properties, we phenomenologically investigate the $${\eta }_{t}$$ $${\rightarrow }$$ $$W^{+}W^{-}$$ process, one of the characteristic decays of toponium $${\eta }_{t}$$ . The branching ratio for the $${\eta }_{t}$$ $${\rightarrow }$$ $$W^{+}W^{-}$$ decay is estimated with two scenarios of the decay constant $$f_{{\eta }_{t}}$$ . It is found that tens of dilepton events from the cascade decays, $${\eta }_{t}$$ $${\rightarrow }$$ $$W^{+}W^{-}$$ $${\rightarrow }$$ $${\ell }^{-}\bar{\nu }_{\ell }{\ell }^{{\prime }+}{\nu }_{{\ell }^{\prime }}$$ with $${\ell }$$ , $${\ell }^{\prime }$$ $$=$$ $\textit{e}$ and $${\mu }$$ , could be experimentally observed, when considering the realistic identification efficiency of the charged lepton and assuming more than $$3{\times }10^{7}$$ $${\eta }_{t}$$ events available at the future HL-LHC. We propose searching for $${\eta }_{t}$$ via the $${\eta }_{t}$$ $${\rightarrow }$$ $$W^{+}W^{-}$$ $${\rightarrow }$$ $${\ell }^{-}\bar{\nu }_{\ell }{\ell }^{{\prime }+}{\nu }_{{\ell }^{\prime }}$$ channel, which features no $\textit{b}$-jets and clean dilepton signatures, thus offering a complementary and potentially more sensitive probe.

We also discuss the <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>σ</mi></math> coupling constant, which is uncertain, dependence of these mass spectra. A lot of bound and resonant states with some quantum numbers are obtained for each <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>σ</mi></math> coupling constant, but these mass spectra depend on the <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>σ</mi></math> coupling constant significantly.
