Charged Lepton Mass Relations in a Supersymmetric Yukawaon Model
According to an idea that effective Yukawa coupling constants Y eff f are given vacuum expectation values 〈Yf 〉 of fields (“Yukawaons”) Yf as Y eff f = yf 〈Yf 〉/Λ, a possible superpotential form in the charged lepton sector under a U(3) [or O(3)] flavor symmetry is investigated. It is found that a specific form of the superpotential can lead to an empirical charged lepton mass relation without ...
متن کاملCharged Lepton Mass Spectrum and Supersymmetric Yukawaon Model
On the basis of the so-called supersymmetric yukawaonmodel, it is investigated what form of the superpotential W can lead to the observed charged lepton mass spectrum. A simple form ofW can speculate reasonable values ofK(μ) = (me+mμ+mτ )/( √ me+ √ mμ+ √ mτ ) 2 and κ(μ) = √ memμmτ/( √ me + √ mμ + √ mτ ) 3 at an energy scale μ = Λ.
متن کاملYukawaon Model in the Quark Sector and Nearly Tribimaximal Neutrino Mixing
For the purpose of deriving the observed nearly tribimaximal neutrino mixing, a possible yukawaon model in the quark sector is investigated. By adjusting two parameters, neutrino mixing parameters sin 2θatm = 0.982, tan 2 θsolar = 0.449 and |U13| = 0.012 are predicted together with reasonable up-quark mass ratios. Also, the CKM mixing parameters and down-quark mass ratios are given under remain...
متن کاملMass Matrix Related to Up - Quark Masses and Nearly Tribimaximal Mixing – Based on a Yukawaon model –
Based on a new approach (the so-called Yukawaon model) to the mass spectra and mixings, a neutrino mass matrix which is described in terms of the up-quark masses and CKM matrix parameters is proposed. The mass matrix successfully leads to a nearly tribimaximal mixing without assuming any discrete symmetry. 1 What is a Yukawaon model? In the standard model of the quarks and leptons, we have many...
متن کاملAn Incentive-Compatible Distributed Recommendation Model
Our research is concerned with the study and development of incentive-compatible exchange mechanisms for recommendations in a multiagent system. These mechanism will allow and motivate agents to create an economy of ideas, where agents trade recommendations between themselves. In this paper we present a domain model and an incentivecompatible protocol for information exchange. Our model capture...
