Koide Mass Equations for Hadrons
Koide mass equations for hadrons Carl Brannen∗1 18500 148th Ave. NE, T-1064, Redmond, WA, USA Email: Carl Brannen∗- [email protected]; ∗Corresponding author Abstract Koide's mass formula relates the masses of the charged leptons. It is related to the discrete Fourier transform. We analyze bound states of colored particles and show that they come in triplets also related by the discrete Fourier transform. Mutually unbiased bases are used in quantum information theory to generalize the Heisenberg uncertainty principle to finite Hilbert spaces. The simplest complete set of mutually unbiased bases is that of 2 dimensional Hilbert space. This set is compactly described using the Pauli SU(2) spin matrices. We propose that the six mutually unbiased basis states be used to represent the six color states R, G, B, R¯, G¯, and B¯. Interactions between the colors are defined by the transition amplitudes between the corresponding Pauli spin states. We solve this model and show that we obtain two different results depending on the Berry-Pancharatnam (topological) phase that, in turn, depends on whether the states involved are singlets or doublets under SU(2). A postdiction of the lepton masses is not convincing, so we apply the same method to hadron excitations and find that their discrete Fourier transforms follow similar mass relations. We give 39 mass fits for 137 hadrons. PACS Codes: 12.40.-y, 12.40.Yx, 03.67.-a 1 Background Introduction The standard model of elementary particle physics takes several dozen experimentally measured characteristics of the leptons and quarks as otherwise arbitrary parameters to the theory.

A Unified Description of Quark and Lepton Mass Matrices in A
A Uniﬁed Description of Quark and Lepton Mass Matrices in a Universal Seesaw Model (a) Yoshio Koide∗†and Hideo Fusaoka‡ Department of Physics, University of Shizuoka, 52-1 Yada, Shizuoka 422-8526, Japan (a) Department of Physics, Aichi Medical University, Nagakute, Aichi 480-1195, Japan (September 16, 2002) In the democratic universal seesaw model, the mass matrices are given by f LmLFR +F LmRfR + F LMF FR (f: quarks and leptons; F : hypothetical heavy fermions), mL and mR are universal for up- and down-fermions, and MF has a structure (1+bf X)(bf is a ﬂavour-dependent parameter, and X is a democratic matrix). The model can successfully explain the quark masses and CKM mixing parameters in terms of the charged lepton masses by adjusting only one parameter, bf . However, so far, the model has not been able to give the observed bimaximal mixing for the neutrino sector. In the present paper, we consider that MF in the quark sectors are still “fully” democratic, while MF in the lepton sectors are partially democratic. Then, the revised model can reasonably give a nearly bimaximal mixing without spoiling the previous success in the quark sectors. PACS numbers: 14.60.Pq, 12.15.Ff, 11.30.Hv I. INTRODUCTION Thus, the model answers the question why the masses of quarks (except for top quark) and charged leptons are so small with respect to the electroweak scale Λ ( A. What is the universal seesaw model? L 102 GeV). On the other hand, the top quark mass en-∼ hancement is understood from the additional condition Stimulated by the recent progress of neutrino experi- detMF = 0 for the up-quark sector (F = U) [2–4].

First of all it is our great pleasure to report the 2008 Nobel physics prize awarded to our former director, Toshihide Maskawa for his contribution to the theory of CP violation. This is the 2nd Nobel prize given to the affiliates of our Institution. We consider that the award exemplifies the high standard of research conducted at our Institute and we would like to maintain our tradition of excellence in research in the future. From the academic year 2007 we started our new project of “Yukawa International Pro- gram of Quark-Hadron Sciences (YIPQS)” funded by Japan Minsitry of Education, Culture and Sports. In this project we select a few research topics in each year and host long-term workshops extending over periods of a few months. We invite leading experts from the world in each topic and aim at fruitful collaboration among the workshop participants. In the year 2007, workshops in the area of the interface of cosmology and string theory, condensed mat- ter theory and also quark hadron physics were held. Our report contains some of the new developments initiated by these workshops.

Universal Texture of Quark and Lepton Mass Matrices and a Discrete Symmetry Z3

Stimulated by this matrix form, the possibility that all the mass matrices of quarks and leptons have the same form as in neutrinos is investigated. The mass matrix form is constrained by a discrete symmetry Z3 and a permutation symmetry S2. The model, of course, leads to a nearly bimaximal mixing for the lepton sectors, while, for the quark sectors, it can lead to reasonable values of the CKM mixing matrix and masses.
