Rapidity gaps and survival probabilities

Ongoing Projects:

• Non-linear evolution and gap survival (Asher Gotsman)

Other proposed subtopics:

• Gaps vs saturation and multiple scatterings
  (They are clearly related, do we have good unified decriptions?)
• Colour neutralization models
  (Where do they work and why? How to model colour connections in multiple scatterings?)
• Saturation models and hadronic collisions
  (Describes ep, can they be applied reliably in pp)
• Perturbative vs non-perturbative
  (Is gaps in DIS really hard, how can we tell, what is the connection to gaps between jets?)
• Models for gap survival
  (What models are there, how are they related, where do they work and not?)
• Final states and jets in gap vs no-gap
  (Very similar in DIS, also in pp?)
• Rescattering/absorption and forward neutrons and protons
  (What can we learn from connecting forward neutron production to forward proton/diffraction?)
• Gaps to get clean Higgs and BSM signals
  (What models are there, how reliable are they, can we improve them, can we learn anything from HERA?)
