Searching for Monopoles via Monopolium Multiphoton Decays
Neil D. Barrie, Akio Sugamoto, Matthew Talia +1
We explore the phenomenology of a model of monopolium based on an electromagnetic dual formulation of Zwanziger and lattice gauge theory. The monopole is assumed to have a finite-s…
Impact of uncertainties in the halo velocity profile on direct detection of sub-GeV dark matter
Andrzej Hryczuk, Ekaterina Karukes, Leszek Roszkowski +1
We use the state-of-the-art high-resolution cosmological simulations by IllustrisTNG to derive the velocity distribution and local density of dark matter in galaxies like our Milky…
Thermal dark matter abundance under non-standard macroscopic conditions in the early universe
Archil Kobakhidze, Michael A. Schmidt, Matthew Talia
The standard theoretical estimation of the thermal dark matter abundance may be significantly altered if properties of dark matter particles in the early universe and at the presen…
Supersymmetric Naturalness Beyond MSSM
Archil Kobakhidze, Matthew Talia
The experiments at the Large Hadron Collider (LHC) have pushed the limits on masses of supersymmetric particles beyond the TeV scale. This compromises naturalness of the simp…
Mechanism for dark matter depopulation
Archil Kobakhidze, Michael A. Schmidt, Matthew Talia
Early decoupling of thermally produced dark matter particles due to feeble interactions with the surrounding plasma typically results in their excessive abundance. In this work we…
Exotic Lepton Searches via Bound State Production at the LHC
Neil D. Barrie, Archil Kobakhidze, Shelley Liang +2
Heavy long-lived multi-charged leptons (MCLs) are predicted by various new physics models. These hypothetical MCLs can form bound states, due to their high electric charges and lon…
Probing the MSSM explanation of the muon g-2 anomaly in dark matter experiments and at a 100 TeV collider
Archil Kobakhidze, Matthew Talia, Lei Wu
We explore the ability of current and future dark matter and collider experiments in probing anomalous magnetic moment of the muon, , within the Minimal Supersymmetric Sta…
Heavy Leptonium as the Origin of the 750 GeV Diphoton Excess
Neil D. Barrie, Archil Kobakhidze, Shelley Liang +2
We propose a hypothetical heavy leptonium, the scalar bound state of an exotic lepton-antilepton pair, as a candidate for the recent 750 GeV resonance in the early LHC Run 2 data.…
750 GeV Composite Axion as the LHC Diphoton Resonance
Neil D. Barrie, Archil Kobakhidze, Matthew Talia +1
We propose that the 750 GeV resonance, presumably observed in the early LHC Run 2 data, could be a heavy composite axion that results from condensation of a hypothetical quark in a…
The Effective MSSM
Archil Kobakhidze, Matthew Talia
We suggest an effective field theory framework to discuss deviations from the minimal supersymmetric Standard Model (MSSM) which is based on an alternative arrangement of the gauge…
