Gravity and Nonlinear Symmetry Realisation

open access: yes, 2020
Application of nonlinear symmetry realisation technique to gravity is studied. We identify the simplest extensions of the Poincare group suitable for nonlinear realisation.

Michaelis-Arbuzov-Type Reaction of 1-Imidoalkyltriarylphosphonium Salts with Selected Phosphorus Nucleophiles

open access: yesMolecules, 2019
In this study, Michaelis-Arbuzov-type reaction of 1-imidoalkyltriarylphosphonium salts with phosphites, phosphonites, and phosphinites was used in the synthesis of a wide range of phosphorus analogs of α-amino acids such as 1-imidoalkylphosphonates,

Probing neutrino and Higgs sectors in $$\text{ SU(2) }_1 \times \text{ SU(2) }_2 \times \text{ U(1) }_Y $$ SU(2) 1 × SU(2) 2 × U(1) Y model with lepton-flavor non-universality

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
The neutrino and Higgs sectors in the $$\text{ SU(2) }_1 \times \text{ SU(2) }_2 \times \text{ U(1) }_Y $$ SU(2) 1 × SU(2) 2 × U(1) Y model with lepton-flavor non-universality are discussed.

A new method for the synthesis of α-aminoalkylidenebisphosphonates and their asymmetric phosphonyl-phosphinyl and phosphonyl-phosphinoyl analogues

open access: yesBeilstein Journal of Organic Chemistry, 2015
A convenient approach has been developed to α-aminoalkylidenebisphosphonates and their asymmetric phosphonyl-phosphinyl and phosphonyl-phosphinoyl analogues by α-phosphonylation, α-phosphinylation or α-phosphinoylation of 1-(N-acylamino)alkylphosphonates,

Insight into the Synthesis and Characterization of Organophosphorus-Based Bridged Triazine Compounds

open access: yesMolecules, 2019
In this article, we report the synthesis of 2,4,6-substituted s-triazine-based organophosphorus compounds via a two-step process, which enables their production in high yields, and with a high purity as solids.

Radiative large-angle Bhabha scattering in collinear kinematics [PDF]

open access: yes, 1999
The process of large-angle high energy electron-positron scattering with emission of one hard photon almost collinear to one of the charged particles momenta is considered.

General one-loop formulas for decay $$h\rightarrow Z\gamma $$ h→Zγ

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Radiative corrections to the decay $$h\rightarrow Z\gamma $$ h→Zγ are evaluated in the one-loop approximation. The unitary gauge is used. The analytic result is expressed in terms of the Passarino-Veltman functions.

Bogoliubov compensation approach in QCD and in the electroweak theory

open access: yes, 2010
We describe application of Bogoliubov compensation principle to calculation of non-perturbative contribution in the electroweak theory and QCD. We obtain unique solutions of compensation equations, which impose strong restrictions on parameters of ...

FCC Physics Opportunities

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We review the physics opportunities of the Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the study of electroweak, Higgs and strong interactions ...

Non-metal-templated approaches to bis(borane) derivatives of macrocyclic dibridgehead diphosphines via alkene metathesis

open access: yesBeilstein Journal of Organic Chemistry, 2018
Two routes to the title compounds are evaluated. First, a ca. 0.01 M CH2Cl2 solution of H3B·P((CH2)6CH=CH2)3 (1·BH3) is treated with 5 mol % of Grubbs' first generation catalyst (0 °C to reflux), followed by H2 (5 bar) and Wilkinson's catalyst (55 °C ...
