Detector performance at SHiP for cascade-produced long-lived particles
Matei Climescu, Yehor Kyselov, Maksym Ovchynnikov
Previous studies have shown that cascade production in the thick target of the SHiP experiment may substantially enhance the number of light long-lived particles (LLPs) decaying in…

New physics particles mixing with mesons: production in the fragmentation chain
Yehor Kyselov, Stephen Mrenna, Maksym Ovchynnikov
A class of extensions to the Standard Model adds hypothetical long-lived particles (LLPs) that have mass- or kinetic-mixing with neutral mesons, such as pions or rho mesons. The mi…

Searches for long-lived dark photons at proton accelerator experiments
Yehor Kyselov, Maksym Ovchynnikov
A systematic and unified analysis of the capability of lifetime frontier experiments to probe the parameter space of hypothetical long-lived particles is crucial for defining the t…
