Probing hadronization with the charge correlator ratio in $p$+$p$, $Ru$+$Ru$ and $Zr$+$Zr$ collisions at STAR
The parton-to-hadron transition, known as hadronization, is dominated by non-perturbative Quantum Chromodynamics (QCD) effects and thus challenging to study from first-principle calculations. On the other hand, experimental studies of observables sensitive to hadronization could provide valuable input. The charge correlator ratio $r_c$ studies the charge correlation between the leading two hadrons in jets and is sensitive to hadronization effects. With data taken at $\sqrt{s_{\rm{NN}}}=200$ GeV…

Precise Predictions for Event Shapes in Hadronic Higgs Decays
We present NNLO QCD predictions for a wide range of event-shape observables in hadronic Higgs decays, taking into account the two dominant decay modes $H\to gg$ and $H\to b\bar{b}$. Specifically, we consider the six classical event shapes thrust, heavy jet mass, $C$-parameter, total and wide jet broadening, and the three-jet resolution $y_{23}$ in the Durham algorithm.We also present results for the soft-drop variant of thrust. Decays of the Higgs boson to two gluons are treated in the heavy-to…

Impact of new measurements of light quarks at hadron colliders
Recently a series of new measurements with both the neutral and charge current Drell--Yan processes have been performed at hadron colliders, showing deviations from the predictions of the current parton distribution functions (PDFs). In this article, the impact of these new measurements is studied by using their results to update the PDFs. Although these new measurements correspond to different boson propagators and colliding energies, they are found to have a similar impact to the light quark …

Charmed hadron production in the QGSJET-III model: relevance to calculations of the prompt atmospheric neutrino background
The treatment of charmed hadron production in the framework of the QGSJET-III Monte Carlo generator is developed, including both perturbative and nonperturbative contributions. For the former, a leading order (LO) perturbative formalism is employed. The so-called $K$-factor designed to take effectively into account higher order corrections, which controls the magnitude of the LO perturbative contribution, is fixed based on a comparison with experimental data on $D$ meson production at the Large…

NNLO QCD Calculation of Hadron Multiplicities in Light-Quark Jets at Lepton Colliders
We present the calculation of next-to-next-to-leading-order (NNLO) QCD corrections to hadron multiplicities in light-quark jets at lepton colliders, employing the ``projection-to-Born" (P2B) method implemented in the FMNLO program. Taking the next-to-leading-order (NLO) result as an example, we rigorously establish the validity of our P2B-based calculation. We then present NNLO predictions for the normalized asymmetry $D_{K^{-}}$ between hadron and antihadron production in light-quark jets and …

Parton distribution and fragmentation functions with massive gluons
The correct description of the hadron's structure requires understanding how quarks and gluons form the observable hadrons and how they are distributed within them. Two key nonperturbative quantities encapsulate this information: parton distribution functions (PDFs) and fragmentation functions (FFs). The former define a probabilistic light-front momentum distribution of partons within a hadron, whereas the latter describe the hadronization process of high-energy partons. Computing these functio…

Hadron-Hadron Interactions from Lattice QCD: Theory meets Experiments
We summarize recent developments in the study of hadron-hadron interactions using lattice QCD near the physical pion mass ($m_π \simeq 146$ MeV), based on the HAL QCD method and its connection to experimental data. In particular, we focus on several key interaction channels shown below. Also, we examine the two-pion exchange (TPE) mechanism, which governs the long-range behavior of interactions between flavor-singlet hadrons, as well as between nucleons and flavor-singlet hadrons.
