Axial-vector transition form factors and e + e − → f 1 π + π −

open access: yesJournal of High Energy Physics, 2023
We study the transition form factors (TFFs) of axial-vector mesons in the context of currently available experimental data, including new constraints from e + e − → f 1(1285)π + π − that imply stringent limits on the high-energy behavior and, for the ...

Initial conditions for electron and photon structure and fragmentation functions

open access: yesJournal of High Energy Physics, 2019
In the computation of short-distance cross sections initiated by electrons and photons one can adopt the so-called structure-function approach, in which these particles play formally the same roles as hadrons do in QCD factorisation theorems, and must ...

On factorisation schemes for the electron parton distribution functions in QED

open access: yesJournal of High Energy Physics, 2021
The electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron have recently been computed at the next-to-leading logarithmic accuracy in QED, by adopting the MS ¯ $$ \overline{\mathrm{MS}} $$ factorisation scheme. We

Increasing the precision for Z production at colliders: mixed QCD-QED effects [PDF]

open access: yesProceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2020
In this talk, we describe the recent progress on the inclusion of mixed QCD-QED corrections for collider observables. In particular, we developed a formalism to extend $q_T$-resummation to deal with simultaneous emission of gluons and photons. We applied it to $Z$ production at colliders, and briefly discuss extensions to more complicated final states.

Radiative corrections to the forward-backward asymmetry in e + e − → π + π −

open access: yesJournal of High Energy Physics, 2022
We present a calculation of the C-odd radiative corrections to e + e − → π + π − in a dispersive formalism, concentrating on the leading pion-pole contribution in the virtual box diagrams.

Cavity QED Based on Strongly Localized Modes: Exponentially Enhancing Single-Atom Cooperativity. [PDF]

open access: yesPhysical Review Letters
Large single-atom cooperativity in quantum systems is important for quantum information processing. Here, we propose to exponentially enhance the single-atom cooperativity parameter by exploiting the strongly localized effect of modes in cavity quantum ...

Unveiling atomic electron motion effects in e + e − high energy collisions at NA64

open access: yesJournal of High Energy Physics
Atomic electron motion is responsible for well-studied effects observed in low-energy (MeV-scale) processes. Recently, interest in this phenomenon has also emerged within the high-energy physics community, due to its potential to increase significantly ...

Regulatory harmonization: Evolution, globalization and future directions

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Regulatory harmonization has become an increasingly important and accepted approach to streamline regulatory review processes and expedite access to safe, effective and high‐quality medicines globally. This review explores the evolution and current status of regulatory harmonization, convergence and reliance initiatives.

Two-loop master integrals for heavy-to-light form factors of two different massive fermions

open access: yesJournal of High Energy Physics, 2018
We calculate the full set of the two-loop master integrals for heavy-to-light form factors of two different massive fermions for arbitrary momentum transfer in NNLO QCD or QED corrections.

The Korea Chemical Bank: Over 25 years of national chemical infrastructure alongside KRICT's 50‐year journey

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This graphic abstract illustrates the role of the Korea Chemical Bank (KCB) as a central national hub that integrates government R&D, academic compound deposits, and industrial drug discovery throughout the latter half of KRICT's 50‐year history. Abstract Since its establishment in 2000 under the Korea Research Institute of Chemical Technology (KRICT),
