H1 and ZEUS have started to combine their inclusive Neutral and Charged Current measurements to test EW unification in the t-channel, complementary to the s-channel primarily investigated at LEP.

H1 + ZEUS combined results:

Electroweak Neutral Currents at HERA (Preliminary) H1 Link , ZEUS Link
(1) Combined NC and CC inclusive crosss sections as a function of Q2 [Eur.Phys.J.C75 (2015) 12, 580]
Combined NC and CC inclusive crosss sections as a function of Q2 [Eur.Phys.J.C75 (2015) 12, 580]
(2) Combined xF3 [Eur.Phys.J.C75 (2015) 12, 580]
Combined xF3 [Eur.Phys.J.C75 (2015) 12, 580]
(3) Combined xF3 at Q2=1000 GeV2 [Eur.Phys.J.C75 (2015) 12, 580]
Combined xF3 at Q2=1000 GeV2 [Eur.Phys.J.C75 (2015) 12, 580]
(4) NC polarisation asymmetry as function of Q² for e⁺p (A⁺) and e^-p (A^-) interactions (preliminary)
