Likelihood-based forward modeling is standard in galaxy formation, but most implementations are formulated as forward maps rather than explicit trajectory-level likelihoods conditioned jointly on assembly history and environment. We introduce a Graph Path Likelihood Model (GPLM) on layered halo graphs, where temporal edges encode causal transport and coeval host edges encode environmental...
Observation of charged lepton flavor violation would constitute unambiguous evidence for physics beyond the Standard Model (SM). We identify a previously unexplored same-sign dimuon signature in electron--photon collisions, $\gamma e^- \to e^+\mu^-\mu^-$, mediated by an axionlike particle (ALP) with flavor-violating $e$--$\mu$ couplings. The absence of irreducible SM backgrounds and the...
In this work we study the prospect of detecting light scalars at the FASER, Mathusla codex-B etc. We develop the general formalism for the scalar production and decay from mesons with PP collision, given modified couplings of the scalars to the SM particles, as well as summarizing the relevant GeV-scale experiment constraints. We then analyze the reaches of light scalars in the large tan𝛽...
