Alternative Large Nc Schemes and Chiral Dynamics

چکیده
We compare the dependences on the number of colors of the leading scattering amplitudes using the single index quark field and two index quark fields. These are seen to have different relationships to the scattering amplitudes suggested by chiral dynamics which can explain the long puzzling pion pion s wave scattering up to about 1 GeV. This may be interesting for getting a better understanding of the large Nc approach as well as for application to recently proposed technicolor models.

We study the decay η ′ → ηππ in two different chiral invariant approaches: Large-Nc Chiral Perturbation Theory (ChPT) and Large-Nc Resonance Chiral Theory (RChT). We analyze the Dalitz plot and the invariant mass spectra. We also compare the relevance of the isoscalar and isovector channels in these approaches. While the predictions of Large-Nc ChPT at next-to-leading order slightly disagree wi...
متن کاملBARYON CHIRAL PERTURBATION THEORY IN THE 1/Nc EXPANSION
The chiral Lagrangian for baryons is formulated in an expansion in 1/Nc. The chiral Lagrangian implements the contracted spin-flavor symmetry of large-Nc baryons as well as nonet symmetry of the leading planar diagrams. Large-Nc consistency conditions ensure that chiral loop corrections are suppressed in 1/Nc through exact cancellation of chiral loop graphs to fixed orders in 1/Nc. Application ...

The large-Nc limit of the meson-baryon effective Lagrangian is shown to reduce to a semiclassical field theory. A chiral bag structure emerges naturally in the Nc → ∞ limit. A possible connection between the chiral bag picture and the Skyrme model is discussed. The classical meson-baryon theory is used to reproduce the M π non-analytic correction to the baryon mass obtained previously as a loop...

The aim of this study is investigating the transport mechanism of ibuprofen chiral isomers inside single wall carbon nano tube (SWCNT) using mathematical modeling. To achieve this goal, molecular dynamics simulation has been performed to evaluate the interactions of ibuprofen isomers with SWCNT in an aqueous solution. Results show that both chiral forms of ibuprofen molecules enter and remain i...

Background: The separation of drug enantiomers in the pharmaceutical industry is of great importance since most organic compounds are chiral. The main purpose of this study was to calculate the binding energy of ibuprofen isomers interacting with the CNT, according to various adsorption configurations. Moreover, we have evaluated the performance of (16.4) chiral carbon nanotube for separation o...
