AI Thread Summary
Three lesser-known equalities in particle physics are presented, highlighting relationships involving the sun's mixing angle, the tau and muon masses, and the Cabibbo angle. Smirnov notes that the sum of the sun and Cabibbo angles equals π/4, while De Vries provides an equality involving the logarithm of tau and muon masses. Additionally, Smirnov suggests a relationship between the square root of the muon and tau masses and the sine of the Cabibbo angle. De Vries also introduces a formula relating the electron and muon masses. The discussion hints at the potential for reformulating these equalities using hyperbolic functions, although this approach may not simplify the understanding.

Three little known equalities:

From Smirnov:
\theta_{\mbox{sun}} + \theta_{\mbox{cabibbo}} = {\pi \over 4}

From De Vries:
\ln {m_\tau \over m_\mu} = \pi - {1 \over \pi}

From Smirnov again:
\sqrt {m_\mu \over m_\tau} \sim \sin \theta_{\mbox{Cab.} }

Can anyone predict them?

de Vries has a secondary formula for the electron-muon relationship, namely
ln(mu/me) / (2pi-3/pi) = 1.000627.

In principle one could recast them in terms of hyperbolic cosines and sines, for instance 1pi-1/pi= 2 sinh(ln(pi)) but it does not clarify the situation.

For instance, taking logarithms we have

\ln (\sin \theta_C) \sim - \sinh (\ln \pi)
