Derivation of a transfer function to estimate the Z(vv)+jets background from photon+jets in a search for dark matter at the ATLAS detector
It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. The most common signature of dark matter production is an excess of missing transverse energy, MET. Such an event would be very rare, which is wh
