The spin of a free electron is stable but its position is not. Recent quantum information research by G. Svetlichny, J. Tolar, and G. Chadzitaskos have shown that the Feynman position path integral can be mathematically defined as a product of incompatible states; that is, as a product of mutually unbiased bases (MUBs). Since the more common use of MUBs is in finite dimensional Hilbert spaces, this raises the question “what happens when spin path integrals are computed over products of MUBs… 
Algebra of Classical and Quantum Binary Measurements
The simplest measurements in physics are binary; that is, they have only two possible results. An example is a beam splitter. One can take the output of a beam splitter and use it as the input of
Quarks, Leptons, and Hopf Algebra Propagators
The weak quantum numbers of the elementary fermions arise as particular representations of the Lie symmetry SU(3)× SU(2)×U(1). Hopf algebras provide a generalization of Lie algebras with the
Informationally Complete Characters for Quark and Lepton Mixings
A d-dimensional Hilbert space with d = c c ( G ) , the number of conjugacy classes of G, is introduced for reproducing simultaneously the CKM (quark) and PNMS (lepton) mixing matrices.
Quantum Information of Unitary Mixing Matrices
Unitary mixing matrices, such as the quark and lepton mixing matrices, have unphysical degrees of freedom; one can multiply rows and columns by arbitrary complex phases. Industry practice is to
Group Geometric Algebras and the Standard Model
We show how to generalize the Weyl equation to include the Standard Model fermions and a dark matter fermion. The 2x2 complex matrices are a matrix ring R. A finite group G can be used to define a
Differential formulation of Schrodinger equation leads to vanishing Berry phase
The Poincare-Hopf theorem states that a globally smooth tangent vector does not exist on a manifold whose Euler characteristic is non-zero. Nevertheless, when one defines a differential equation on

Density Matrices and the Standard Model
We use density matrices to explore the possibility that the various flavors of quarks and leptons are linear superpositions over a single particle whose symmetry follows the finite subgroup $S_4$ of
Improving the Accuracy of Yoshio's Formula Koide
The formula Yoshio Koide, shows a pretty compelling link between the masses of leptons: electron, muon, tauon. We offer a clear improvement in accuracy in expressing this formula electron unit. This
A possible origin of the q=4/3 diquark
Between the new physics candidates proposed to explain the $t \bar t$ asymmetry measured in the Tevatron, there are some scalar diquarks with electric charge +4/3. This kind of diquark is also needed


Feynman's path integral and mutually unbiased bases
Our previous work on quantum mechanics in Hilbert spaces of finite dimension N is applied to elucidate the deep meaning of Feynman's path integral pointed out by G Svetlichny. He speculated that the

Recently it has been proposed that a strange logarithmic expression for the so-called Barbero-Immirzi parameter, which is one of the ingredients that are necessary for Loop Quantum Gravity (LQG) to

A quantal system in an eigenstate, slowly transported round a circuit C by varying parameters R in its Hamiltonian Ĥ(R), will acquire a geometrical phase factor exp{iγ(C)} in addition to the familiar
Introduction to complex orbital momenta
SummaryIn this paper the orbital momentumj, until now considered as an integer discrete parameter in the radial Schrödinger wave equations, is allowed to take complex values. The purpose of such an
All three charged lepton pole masses are given to O(10-5) accuracy by $(m_e, m_\mu, m_\tau)=(313.85773~{\rm MeV})[1+\sqrt{2}\,{\rm cos}\,\theta_k]^2$, where θk = 2πk/3 + 2/9 with the generation
The Lepton Masses
In the standard model, the lepton masses appear as arbitrary constants determined by experiment. But in 1982, Yoshio Koide proposed a formula for the charged lepton masses that is still going strong

Recent Results from the MINOS Experiment
The MINOS experiment utilizes the NuMI beam of muon neutrinos to study the phenomenon of neutrino oscillations. Neutrinos are sent over a baseline of 735 km, with a detector near the production point
