Imbalance in-line with showers of particles

  • Whoandwhatitis by Whoandwhatitis moderator

    I have seen a few of these images where the red dashed line (the measured imbalance of momentum) is perfectly in line with showers of particles. I think this is a neat type of picture. Is this something that should be marked as weird?

    In this case, we see two #ocv coming from near this line, and each OCV has four lines. Most of the energy on the calorimeters is focused in this area.

    Yes, you could mark this as weird. It's important that the missing momentum is aligned with the ocv's. That's a sign that some non-interacting particles (dark matter?) could be being produced along with those ocv's!
    (I think this one is sim though...)
