double stack | two stacks separated by little distance. |
layer | one stack. |
pileup | occurrence of more than one proton-proton collision during a given time interval of interest. In general, the time interval of interest is a single bunch crossing; the "interesting" collision is usually the one with particles of largest transverse momenta, while the others are the "pileup" collisions. That is then the "in-time" pileup Notice that, due to buffering, collisions from both previous and future bunch crossings can contribute to a given interval of interest - that is then referred as "out-of-time" pileup. |
stack | tuple of closely spaced sensors.
|
stack member | sensor of stack |
stub | correlated pair of hits in stack.
|
threshold | selecting path by min number of stubs matched. |
tracklet | matched pair of stubs. |
