We extend the work of [1] to the case in which final-state jets, produced in association with a Higgs or vector boson, are defined using the $\textit{k}$ algorithm. We thereby compute the full distribution of the invariant mass squared of the leading, highest-$\textit{p}$ jet, including both clustering and non-global logarithms, up to four-loops in perturbation theory. Our results are derived within the eikonal approximation under the assumption of strong ordering in the momenta of the final-state partons, and are consequently valid up to single-logarithmic accuracy. The final semi-analytical expressions retain the complete dependence on both colour and the jet radius. The broad features of $\textit{k}$ clustering observed in $\textit{e}$ $\textit{e}$ processes persist in hadronic collisions, together with novel characteristics that are absent in the $\textit{e}$ $\textit{e}$ environment.

In the framework, flavor SU(3) symmetry breaking effect is incorporated into the topological amplitudes, allowing the nonfactorizable contributions from topological diagrams to be expressed as a minimal set of universal parameters determined through a global fit to experimental data. Thanks to the sufficient data with high precision, we are now able to quantify the nonfactorizable contribution of so-called “factorization” <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>T</mi></math> diagram, which is essential for explaining the observed branching ratios. The parameters for the <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>C</mi></math>, <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>E</mi></math>, and <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>A</mi></math> diagrams are also updated with significant improved precision, and notably, the resulting strong phases differ substantially from those in the earlier FAT analysis. We find that the <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>C</mi></math> topological amplitude features substantial nonfactorizable effects in the charm sector. These refined parameters enable predictions of significantly improved accuracy, yielding branching ratios in good agreement with current data and the latest results in topological diagram approach, and the predicted direct <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><mi>C</mi><mi>P</mi></mrow></math> asymmetries differ distinctly form previous FAT results due to updated strong phases.

We study a <italic>d</italic>-dimensional Anti-de Sitter (AdS) black hole surrounded by a static anisotropic quintessence field within the framework of Rastall theory. The solution is characterized by several parameters including its mass ( <italic>M</italic>), field structure parameter ( <italic>N<inf>s</inf></italic>), Rastall coupling parameter ( <italic>&#968;</italic>), and the cosmological constant (&#923;). Our objective here is to identify the <italic>d</italic>-dimensional black holes within the framework of Rastall theory, exploring special cases, e.g., a cosmological constant, dust, radiation, and quintessence fields. In addition to this, we derive the effective equation of state parameter, denoted as <italic>&#969;<inf>eff</inf></italic>. Next, we investigate the thermodynamics for <math altimg='si15.svg'><mrow><mi>P</mi><mspace width='0.16em' /><mo linebreak='goodbreak'>&#8722;</mo><mspace width='0.16em' /><mi>V</mi></mrow></math> criticality and phase transitions in the extended phase space of black hole thermodynamics. For a specific set of values for the Rastall coupling parameter, we numerically plot isothermal and isobaric curves in the reduced parameter space. We also compute the specific heat at constant pressure ( <italic>C<inf>P</inf></italic>), volume expansion coefficient ( <italic>&#945;</italic>), and isothermal compressibility ( <italic>&#954;<inf>T</inf></italic>) to deepen our understanding of the analogy between the thermodynamics of Rastall AdS black holes and that of a liquid-gas system. Our investigations indicate that the dimension of spacetime and the Rastall coupling parameter significantly influence the critical nature of phase transitions. By utilizing the expressions for <italic>C<inf>P</inf>, &#945;</italic>, and <italic>&#954;<inf>T</inf></italic>, we derive the Ehrenfest equations and perform an analytical investigation of phase transitions at their critical points. These results allow us to compare the thermodynamics of AdS black holes with liquid-gas systems, which closely mimics the behavior of van der Waals (vdWs) gases. We briefly discuss the off-shell Gibbs free energy in various spacetime dimensions for different values of the Rastall coupling parameter <italic>&#968;</italic>.

The top-quark Yukawa coupling is extracted from the distribution of the top-quark pair ( $$ t\overline{t} $$ ) invariant mass in proton-proton collisions using 140 fb of data at $$ \sqrt{s}=13 $$ TeV collected in 2015–2018 by the ATLAS experiment at the Large Hadron Collider. In the region near the production threshold, the $$ t\overline{t} $$ invariant mass spectrum is sensitive to electroweak virtual corrections, including contributions from Higgs boson exchange, thereby providing sensitivity to the top-quark Yukawa coupling. This is the first measurement in ATLAS that aims to obtain this coupling exploiting this approach. The $$ t\overline{t} $$ system is reconstructed in the single-lepton final state, requiring exactly one isolated electron or muon and at least four jets with at least two identified as originating from $\textit{b}$-quarks. The measured Yukawa coupling is found to be in good agreement with the Standard Model prediction. An upper limit on the top-quark Yukawa coupling strength of $\textit{Y}$ $\textit{<}$ 2$\textit{.}$1 relative to the Standard Model prediction is observed at 95% confidence level, consistent with the expected sensitivity.

We propose a novel method to detect reactor $ \overline{\nu}^{}_e \to \overline{\nu}^{}_\mu $ and $ \overline{\nu}^{}_e \to \overline{\nu}^{}_\tau $ oscillations by using elastic antineutrino-electron scattering processes $ \overline{\nu}^{}_\alpha + e^- \to \overline{\nu}^{}_\alpha + e^- $ (for $ \alpha = e, \mu, \tau $ ), among which the $ \overline{\nu}^{}_e $ events can be singled out by accurately measuring the $ \overline{\nu}^{}_e $ flux via the inverse beta decay $ \overline{\nu}^{}_e + p \to e^+ + n $ . A proof-of-concept study shows that such measurements will not only be able to test the conservation of probability for reactor antineutrino oscillations, but also offer a new possibility to probe leptonic CP violation at the one-loop level.

In this work, we discuss both relativistic and perturbative QCD corrections to the transition form-factor $$\mathcal{F}_{\eta _Q}{(t_1,t_2)}$$ for the process $$\gamma ^*(q_1) \gamma ^*(q_2) \leftrightarrow \eta _Q(P)$$ with dependencies on the normalised photon virtualities $$t_1=q_1^2/m_Q^2$$ and $$t_2=q_2^2/m_Q^2$$ , where $$m_Q$$ is the heavy quark mass. We resum a class of relativistic corrections to all orders in the relativistic parameter $$\langle v^2 \rangle _{\eta _Q}$$ . In addition, we include perturbative QCD corrections up to next-to-next-to-leading order (NNLO) in the strong coupling constant $$\alpha _s$$ . This involves the computation of two-loop amplitudes with two off-shell photons. We explore three different phenomenological applications of our transition form-factors for the charmonium case. We first study the ratio $$\vert \mathcal{F}_{\eta _c}{(t_1,0)} \vert / \vert \mathcal{F}_{\eta _c}{(0,0)} \vert $$ for the single space-like photon case and compare our results with the existing $$\eta _c$$ measurements from the collaboration. Secondly, we consider observables for the case of double space-like photons and discuss the impact of the different corrections. The NNLO corrections for this case are presented here for the first time in the literature. Finally, we revisit the decay width $$\Gamma [\eta _c \rightarrow \gamma \gamma ]$$ and compare it with the existing PDG value.
