Exclusivity of p-N interactions within p-A collisions.
A geometric Glauber model applied to p-p or p-A collisions assumes that participant partons within a projectile nucleon independently follow eikonal trajectories, just as for projectile nucleons within target nuclei, and interact independently with any target nucleons encountered along their trajectory. A noneikonal quadratic relation for dijet production observed for p-p collisions suggests that such assumptions for p-N collisions may be incorrect. Data from p-A collisions supports that conclusion. For both isolated p-p collisions and for p-N interactions within p-A collisions a proton projectile interacts with only a single target nucleon within a brief time interval. Multiple overlapping p-N collisions are inhibited, suggesting the exclusivity of p-N interactions within p-A collisions.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
