(Melissa gave us a great Journal Club about this last year)</div><div>- Why is the proton decay a constraint?</div><div>- How can they constrain the dark particle mass and properties of the decay?</div><div>- What differences are between models 1 and 2?</div><div>- What are the implications if dark matter particles have a similar mass to nucleons?</div><div>- Can we test any of these hypothesis at
