Colder Freeze-in Axinos Decaying into Photons
Kyu Jung Bae, Ayuki Kamada, Seng Pei Liew +1
We point out that 7 keV axino dark matter (DM) in the R-parity violating (RPV) supersymmetric (SUSY) Dine-Fischler-Srednicki-Zhitnitsky model can simultaneously reproduce the 3.5ke…
Light Axinos from Freeze-in: production processes, phase space distributions, and Ly- forest constraints
Kyu Jung Bae, Ayuki Kamada, Seng Pei Liew +1
We consider freeze-in production of 7 keV axino dark matter (DM) in the supersymmetric Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) model in light of the 3.5 keV line excess. The warm…
Mono-X Versus Direct Searches: Simplified Models for Dark Matter at the LHC
Seng Pei Liew, Michele Papucci, Alessandro Vichi +1
We consider simplified models for dark matter (DM) at the LHC, focused on mono-Higgs, -Z, or -b produced in the final state. Our primary purpose is to study the LHC reach of a rela…
Effects of QCD bound states on dark matter relic abundance
Seng Pei Liew, Feng Luo
We study scenarios where there exists an exotic massive particle charged under QCD in the early Universe. We calculate the formation and dissociation rates of bound states formed b…
Models of 750 GeV quarkonium and the LHC excesses
Koichi Hamaguchi, Seng Pei Liew
We investigate models involving a vector-like quark X, which forms a 750 GeV bound state and reproduces the observed diphoton signals at the LHC, in connection with other excesses…
Testing ATLAS Diboson Excess with Dark Matter Searches at LHC
Seng Pei Liew, Satoshi Shirai
The ATLAS collaboration has recently reported a 2.6 sigma excess in the search for a heavy resonance decaying into a pair of weak gauge bosons. Only fully hadronic final states are…
