Abstract: | We study dark matter production at CERN LHC from black hole remnants (BHR). We find that the typical mass of these BHR at
the LHC is ∼5–10 TeV which is heavier than other dark matter candidates, such as axion, axino, neutralino, etc. We propose
the detection of this dark matter via single jet production in the process pp → jet + BHR (dark matter) at CERN LHC. We find that for zero impact parameter partonic collisions, the monojet cross section
is not negligible in comparison to the standard model background and is much higher than the other dark matter scenarios studied
so far. We also find that dσ/dp
T
of jet production in this process increases as p
T
increases, whereas in all other dark matter scenarios the dσ/dp
T
decreases at CERN LHC. This may provide a useful signature for dark matter detection at the LHC. However, we find that when
the impact parameter dependent effect of inelasticity is included, the monojet cross section from the above process becomes
much smaller than the standard model background and may not be detectable at the LHC. |
