    The LHC produces a vast sample of top quark pairs and single top quarks. Measurements of the inclusive top quark production rates at the LHC have reached a precision of several percent and test advanced Next-to-Next-to-Leading Order predictions in QCD. Differential measurements in several observables are important to test SM predictions and improve Monte Carlo generator predictions. In this...

    Effective Field Theory (EFT) provides a universal framework for probing beyond the Standard Model physics at LHC scales.

    The exceptionally large dataset collected by the ATLAS and CMS detectors at the highest proton-proton collision energies provided by the LHC enables precision testing of theoretical predictions using an extensive sample of top quark events. One example of this is the spin correlation of top quarks, which can uniquely be probed due to the decay time being shorter than hadronisation time. This...

    Jose Enrique Palencia Cortezon (Universidad de Oviedo (ES))

    A violation of the charge-parity (CP) symmetry can explain the paradox of the baryon asymmetry of the universe. We have studied a forward-backward asymmetry of an angular distribution defined in the top quark sector, which is strongly related to the CP-violation. The measurement is performed in the t-channel production of single top quark in proton-proton collisions, at center-of-mass energy...

    We present analytic expressions for the one-loop QCD helicity amplitudes contributing to top-quark pair production in association with a photon or a jet at the Large Hadron Collider (LHC), evaluated through $O(\epsilon^2)$ in the dimensional regularisation parameter, $\epsilon$. These amplitudes are required to construct the two-loop hard functions that enter the NNLO QCD computation. The...

    Mr Syed Haider Ali (Department of Physics & Applied Mathematics, Pakistan Institute of Engineering and Applied Sciences (PIEAS), P. O. Nilore 45650, Islamabad)

    Rare event classification in high-energy physics (HEP) plays a crucial role in probing physics beyond the Standard Model (BSM). Such processes serve as indirect searches for new physics by testing deviations from SM predictions in extreme kinematic regimes. The production of four top quarks in association with a ($W^-$) boson at $(\sqrt{s} = 13)$ $ TeV$ is an exceptionally rare SM process with...

    We will report on an extensive survey of rare and exclusive few-body decays of the top quark, defined as those with branching fractions BR≲$10^{-5}$ and two or three final-state particles [1]. Such rare decays probe physics beyond the Standard Model (BSM), constitute a background for exotic decays into new BSM particles, and provide precise information on quantum chromodynamics factorization...

    The top-quark mass is one of the key fundamental parameters of the Standard Model that must be determined experimentally. Its value has an important effect on many precision measurements and tests of the Standard Model. The Tevatron and LHC experiments have developed an extensive program to determine the top quark mass using a variety of methods. In this contribution, the top quark mass...

    We study the single top plus Higgs production process at the LHC with a CP violating Yukawa coupling from a dimension-6 operator. The amplitude of the subprocess ub>dtH is obtained both in the Unitary (U) and Feynman-Diagram (FD) gauges. Energy and angular distributions of the cross section and CP violating asymmetries are understood from the interference among the FD gauge amplitudes.

    JINHEUNG KIM
    Poster

    Many Beyond the Standard Model (BSM) theories predict new scalar bosons 𝜙 that couple to top quarks. Such scalars contribute to $gg\to t\bar{t}$ production via $gg\to \phi^* \to t\bar{t}$, leading to significant interference with the Standard Model $gg\to t\bar{t}$ amplitude. Near the $t\bar{t}$ threshold, top quark pairs form bound states, requiring careful theoretical treatment of the...

    We present the first analytic results of next-to-next-to-next-to-leading-order (N3LO) QCD corrections to the top-quark decay width. We focus on the dominant leading color contribution, which includes light-quark loops. At next-to-next-to-leading order (NNLO), this dominant contribution accounts for 95% of the total correction. By utilizing the optical theorem, the N3LO corrections are related...

    The Future Circular Collider (FCC) programme provides unique opportunities for comprehensive and precise studies of top quark physics. At the FCC-ee, operating at and slightly above the top pair threshold, a precise measurement of the top quark mass with a statistical and systematic accuracy down to the MeV level can be achieved through a threshold scan. Furthermore, the FCC-ee run at 365 GeV...

  108. 70. Top-quark pair production and decay: toward NNLO+PS accuracy
    Chiara Signorile

    In this presentation, we will discuss recent advancements in NNLO+PS predictions for top-quark pair production and decay within the MiNNLO framework. MiNNLO provides a robust method for incorporating next-to-next-to-leading order (NNLO) QCD corrections directly into fully differential predictions, offering unprecedented accuracy. This approach enables a consistent treatment of both production...

  110. 71. Towards a NNLO+PS generator for ttH production in POWHEG
    Christian Biello (Max-Planck Institute for Physics)

    The current MiNNLOPS technology enables next-to-next-to-leading order (NNLO) QCD predictions matched to parton showers (NNLO+PS) for heavy-quark pair production in arbitrary kinematics (QQF), within the POWHEG framework. Among QQF processes, Higgs production in association with a heavy-quark pair is particularly relevant for LHC phenomenology. In the case of ttH production, the main bottleneck...

  111. 79. Two-loop Integrals for leading colour ttW production
    Dhimiter Canko (Università di Bologna)
    Poster

    We present the calculation of two-loop Feynman integrals contributing to NNLO QCD corrections to the production of a top-quark pair in association with a W boson at hadron colliders, in the leading colour approximation. This process constitutes a key signature at the Large Hadron Collider, and the precise prediction of its cross-section is imperative for comparisons with experimental data. In...

  112. 78. Two-loop QCD corrections for radiative top decay process
    Colomba Brancaccio
    Poster

    I will present the calculation of two-loop QCD amplitudes for the radiative top decay process t->Wbg, with the W-boson decay to a lepton-neutrino pair included. This amplitude is required in the computation of top quark pair production in association with a jet at NNLO QCD accuracy where the top decays are included in the narrow width approximation. Analytic form of the two-loop helicity...
