Indirect detection constraints on semi-annihilation of inert scalar multiplets
Hugues Beauchesne, Cheng-Wei Chiang
Certain models of inert multiplets allow for semi-annihilation processes, in which two dark matter candidates annihilate to a dark matter particle and a non-dark matter particle. T…
Dark matter semi-annihilation for inert scalar multiplets
Hugues Beauchesne, Cheng-Wei Chiang
Dark matter semi-annihilation is a process through which two dark matter candidates annihilate to a single dark matter particle and a non-dark matter particle. Such processes are c…
Impact of non-thermal phase-space distributions on dark matter abundance in secluded sectors
Hugues Beauchesne, Cheng-Wei Chiang
Many new physics models include secluded sectors that interact little with the Standard Model and whose internal interactions control the dark matter abundance. If these same inter…
Improving the performance of weak supervision searches using transfer and meta-learning
Hugues Beauchesne, Zong-En Chen, Cheng-Wei Chiang
Weak supervision searches have in principle the advantages of both being able to train on experimental data and being able to learn distinctive signal properties. However, the prac…
