Mix<strong>in</strong>g angles are be<strong>in</strong>g probed by oscillation experiments:<br />
i) Atmospheric angle almost maximal: s<strong>in</strong> 2 2θ23 ∼ 1<br />
ii) Solar angle close to maximal: s<strong>in</strong> 2 2θ12 ∼ 0.8<br />
iii) Reactor angle not measured: s<strong>in</strong> 2 2θ13 < 0.16<br />
θ23 and θ12 much larger than mix<strong>in</strong>g angles <strong>in</strong> <strong>the</strong><br />
quark sector<br />
