چکیده

We introduce Weinberg’s idea of asymptotic safety and pave the way towards an asymptotically safe chiral Yukawa system with a U(NL)L⊗U(1)R symmetry in a leading-order derivative expansion using nonperturbative functional RG equations. As a toy model sharing important features with the standard model we explicitely discuss NL = 10 for which we find a non-Gaußian fixed point and compute its critical exponents. We observe a reduced hierarchy problem as well as predictions for the toy Higgs and the toy top mass.

Charged fermion states in the quenched U(1) chiral Wilson-Yukawa model

Property of charged fermion states is investigated in the quenched U(1) chiral Wilson-Yukawa model. Fitting the charged fermion propagator with a single hyperbolic cosine does not yield reliable results. On the other hand the behavior of the propagator including large lattice size dependence is well described by the large Wilson-Yukawa coupling expansion, providing strong evidence that no charg...

Asymmetric Synthesis of New Diastereomerically Pure Spiro Oxindolopyrrolizidines and Oxindolopyrrolidines via Cycloaddition Reactions of Azomethine Ylides and Menthol-Drived Trans-Cinnamic

Chiral pyrrolidines and pyrrolizidines with spirooxindole ring systems are the central skeletons for numerous alkaloids and pharmacologically important compounds. Gelesmine, pseudotabersonine, formosanine, isoformosanine, morroniside and mitraphylline are some of the alkaloids containing spirooxindole ring systems. Derivatives of spirooxindole find very wide biological applications as anti micr...

A novel synthesis of diastereomerically pure spiro- oxindolopyrrolizidines and oxindolopyrrolidines via cycloaddition reactions of azomethine ylides

An efficient one-pot three-component procedure for the synthesis of new chiral spiro oxindolopyrrolidines/pyrrolizidines with highly regio- and diastereo-enantio, selective from 1,3-dipolar cycloaddition of azomethine ylides and chiral menthol-drived trans-cinnamic are described. The mechanism of the reaction is discussed on basis of the assignment of the absolute configuration of one of the cy...

On the phase structure of a chiral invariant Higgs-Yukawa model

In the past the construction of Higgs-Yukawa models on the lattice was blocked by the lack of a consistent definition of a chiral invariant Yukawa coupling term. Here, we consider a chiral invariant Higgs-Yukawa model based on the overlap operator D (ov) realized by the NeubergerDirac operator. As a first step towards a numerical examination of this model we study its phase diagram by means of ...
