Modification of chiral dimethyl tartrate through transesterification : immobilisation on POSS and enantioselectivity reversion in Sharpless asymmetric epoxidation [PDF]

, 2010
Modification of dimethyl tartrate has been investigated through transesterification with aminoalcohols to provide reactive functionalities for the covalent bonding of chiral tartrate to polyhedral oligomeric silsesquioxanes.

Decays τ → ππηντ and τ → πηηντ in the extended Nambu–Jona-Lasinio model

Natural Science Review
In the framework of the extended Nambu–Jona-Lasinio model, the processes τ → ππη(η′)ντ and τ → πηη(η′)ντ are considered taking into account mesons in the ground and first radially excited intermediate states. It is shown that in the processes τ → ππη(η′)

Lagrangians for massive Dirac chiral superfields

Nuclear Physics B, 2016
A variant for the superspin one-half massive superparticle in $ 4D $, $ \mathcal{N}=1 $, based on Dirac superfields, is offered. As opposed to the current known models that use spinor chiral superfields, the propagating fields of the supermultiplet are those of the lowest mass dimensions possible: scalar, Dirac and vector fields.

Refining the scalar and tensor contributions in τ → πππν τ decays

Journal of High Energy Physics, 2017
In this article we analyze the contribution from intermediate spin-0 and spin-2 resonances to the τ → νπππ decay by means of a chiral invariant Lagrangian incorporating these mesons.

Optical properties of planar chiral meta-materials [PDF]

, 2002
The polarization state of visible light is found to be altered upon reflection from artificial two-dimensional chiral media. Arrays of metallic planar chiral structures were fabricated by electron beam lithography and ion beam milling. The characteristic

Hidden-charm and hidden-bottom molecular pentaquarks in chiral effective field theory

Journal of High Energy Physics, 2019
The newly observed P c (4312), P c (4440) and P c (4457) at the LHCb experiment are very close to the Σ c D ¯ $$ {\varSigma}_c\overline{D} $$ and Σ c D ¯ ∗ $$ {\varSigma}_c{\overline{D}}^{\ast } $$ thresholds.
