Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...

W-propagator corrections to muon and tau leptonic decays

open access: yes, 2013
We derive the corrections induced by the W-boson propagator to the differential rates of the leptonic decay of a polarized muon and tau lepton. Results are presented both for decays inclusive of inner bremsstrahlung as well as for radiative ones, when a ...

NJL interaction derived from QCD: vector and axial-vector mesons

open access: yes, 2008
In previous works effective non-local $SU(2)\times SU(2)$ NJL model was derived in the framework of the fundamental QCD. All the parameters of the model are expressed through QCD parameters: current light quark mass $m_0$ and average non-perturbative ...

Hadronic Cross Sections in Electron-Positron Annihilation with Tagged Photon [PDF]

open access: yes, 1998
Events with tagged photons in the process of electron-positron annihilation into hadrons are considered. The initial state radiation is suggested to scan the hadronic cross section with the energy. QED radiative corrections are taken into account.

Analytic Invariant Charge in QCD

open access: yes, 2003
This paper gives an overview of recently developed model for the QCD analytic invariant charge. Its underlying idea is to bring the analyticity condition, which follows from the general principles of local Quantum Field Theory, in perturbative approach ...

Von Neumann's Quantization of General Relativity

open access: yes, 2016
Von Neumann's procedure is applied for quantization of General Relativity. We quantize the initial data of dynamical variables at the Planck epoch, where the Hubble parameter coincides with the Planck mass.

From Hadronic Cross Section to the measurement of the Vacuum Polarization at KLOE: a fascinating endeavour [PDF]

open access: yes, 2017
The KLOE experiment at the $\phi-factory$ DA$\Phi$NE in Frascati is the first to have employed Initial State Radiation (ISR) to precisely determine the $e^+e^-\to\pi^+\pi^-(\gamma)$ cross section below 1 GeV.

Catalysis in Chemical Modification of Proteins

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Catalytic principles of synthetic organic chemistry have been increasingly applied to chemical modification of proteins during the recent years. This review article describes how seven types of catalytic systems —electrocatalysis, photocatalysis, metal catalysis, acid catalysis, organocatalysis, supramolecular catalysis, and heterogeneous catalysis ...

Deep Inelastic Scattering with Tagged Initial State Radiation: Complete O(alpha) leptonic QED Corrections

open access: yes, 2001
In this paper we extend the calculation of the QED corrections to deep inelastic lepton-proton scattering with a tagged photon, taking into account the full corrections on the lepton side.
