These combinations are performed per centre-of-mass energy and for each production mode: $t$-channel, $tW$, and $s$-channel.

The method is based on the measurement of dilepton production from the $\gamma p\rightarrow\ell^+\ell^-+X$ reaction in proton--lead collisions.

It opened a landscape of possibilities in the study of Higgs boson properties, Electroweak Symmetry breaking and the Standard Model in general, as well as new avenues in probing new physics beyond the Standard Model.

In distinction to coherent diffraction, the nucleus is allowed to break up, but except for the vector meson no new particles are produced in the reaction [...] OpenAccess: PDF PDF (PDFA); 2019-01-2812:44 [PUBDB-2019-00782] Preprint/Report et al The Tensor Pomeron and Low-x Deep Inelastic Scattering [arXiv:1901.08524; MPP-2018-301; DESY 19-002]   The tensor-pomeron model is applied to low-x deep-inelastic lepton-nucleon scattering and photoproduction.
