Three doublet lepton-specific model

Search for a nearly degenerate lepton doublet (L-,L0).

. We have searched for a heavy charged lepton with an associated neutrino of nearly the same mass in e+eannihilation data taken with the Mark II detector at a centerof-mass energy of 29 GeV. In order to suppress contamination from conventional two.photon reactions, this analysis uses a novel, radiative-tagging technique. Requiring . the presence of an isolated, energetic photon allows a search ...

Phenomenology of the two Higgs doublet sector of a quark-lepton symmetric model.

In the simplest examples of models with a discrete quark-lepton symmetry, an electroweak symmetry breaking sector with more than one Higgs doublet is necessary to obtain the correct mass relations between quarks and leptons. A two Higgs doublet model version has flavour-nonconserving Yukawa couplings, which are proportional to the masses of the quark-lepton symmetric partners of the fermions. W...

Lepton Flavor Violation in the Two Higgs Doublet Model type III

We consider the Two Higgs Doublet Model (2HDM) of type III which leads to Flavour Changing Neutral Currents (FCNC) at tree level in the leptonic sector. In the framework of this model we can have, in principle, two situations: the case (a) when both doublets acquire a vacuum expectation value different from zero and the case (b) when only one of them is not zero. In addition, we show that we ca...

patient‐specific three‐dimensional model

Background: The aim of this study is to provide better insights into the cerebral perfusion patterns and collateral mechanism of the circle of Willis (CoW) under anatomical and pathological variations. Methods: In the current study, a patient-specific three-dimensional computational model of the CoW was reconstructed based on the computed tomography (CT) images. The Carreau model was applied to...
