A spin on same-sign W-boson pair production

Understand

We demonstrate that the LHC will be sensitive to quantum correlations between two quarks inside the proton.

• Same-sign W-boson pair production is the most promising channel for clear measurements of double parton scattering.
• The left-handed nature of the coupling between quarks and W-bosons makes it a prime probe to measure parton spin correlations.
• We perform a detailed analysis of double parton scattering, including relevant backgrounds.
