Exporting dark QCD via different portal models at the LHC is an exciting prospect. As we known, the dark gluon($g_v$) is an indispensable ingredient in dark QCD. However, the popular two dark showers event with two dark quarks ($q_v\overline{q_v}$) in the final state cannot directly look for the evidence of dark gluon at the LHC. Inspired from the $e^+e^-\rightarrow q\overline{q}g$ process at...
In this work, several jet substructure observables have been examined to compare semi-visible jets and light quark/gluon jets. These comparisons were performed using different dark hadron fraction in the semi-visible jets (signal). The extreme scenarios where signal consists either of entirely dark hadrons or visible hadrons offers a chance to understand the effect of the specific dark shower...
I will talk about work in progress with Simon Knapen and Dong Xu on benchmark model building to support a proposed inclusive search strategy for dark shower searches. We discuss the relevant signature space, with particular focus on production through low-mass portals such as the Higgs boson. We plan to publish a Monte Carlo repository containing several selected benchmark models as part of...
I will present a pythia 8 plugin which generates events for strongly coupled, quasi-conformal hidden valleys, also known as "soft bombs" or "Soft Unclustered Energy Patterns (SUEP)". The code can be extended easily to handle other dark showers that are currently not yet included in pythia 8.
