Upgrading the SuperKEKB electron-positron collider with polarized electron beams opens a new program of precision physics at center-of-mass energy 10.58 GeV. This white paper describes potential this `Chiral Belle' program. It includes projections for measurements $\sin^2\theta_W$ that can be obtained from independent left-right asymmetry $e^+e^-$ transitions to pairs electrons, muons, taus, charm and b-quarks. The obtainable will match LEP/SLC world average, but centre-of-mass Measurements...
A bstract Dark matter from a hidden sector with SU( N ) gauge symmetry can have nonabelian kinetic mixing portal the standard model. The dark photon becomes massive in confining phase without need for spontaneous breaking. Depending on particle content of sector, there be two or more composite vectors that get through heavy mediator X . This provides model photons giving direct detection baryons. Avoiding exotic charged relics requires additional couplings allowing to decay quarks and...
Dark matter from a hidden sector with SU($N$) gauge symmetry can have nonabelian kinetic mixing portal the standard model. The dark photon becomes massive in confining phase without need for spontaneous breaking. Depending on particle content of sector, there be two or more composite vectors that get through heavy mediator $X$. This provides model photons giving direct detection baryons. Avoiding exotic charged relics requires additional couplings allowing $X$ to decay quarks and fields,...
