Exclusive photoproduction of light and heavy vector mesons: thresholds to very high energies
A reaction model for $γ+ p \to V + p$, $V=ρ^0, ϕ, J/ψ, Υ$, which exposes the quark-antiquark content of the photon in making the transition $γ\to {q} \bar{q} + \mathbb P \to V$, where ${q}$ depends on $V$, and couples the intermediate ${q} \bar{q}$ system to the proton's valence quarks via Pomeron ($\mathbb P$) exchange, is used to deliver a unified description of available data -- both differential and total cross sections -- from near threshold to very high energies, $W$, for all the $V…

RELATE-Sim: Leveraging Turning Point Theory and LLM Agents to Predict and Understand Long-Term Relationship Dynamics through Interactive Narrative Simulations
Most dating technologies optimize for getting together, not staying together. We present RELATE-Sim, a theory-grounded simulator that models how couples behave at consequential turning points-exclusivity talks, conflict-and-repair episodes, relocations-rather than static traits. Two persona-aligned LLM agents (one per partner) interact under a centralized Scene Master that frames each turning point as a compact set of realistic options, advances the narrative, and infers interpretable state cha…

Sterile neutrino dark matter from a TeV Scale Seesaw
In this article, we investigate the phenomenological aspects of a feebly interacting sterile neutrino dark matter in a low-scale seesaw setup. The Type-I seesaw framework is augmented by a second complex scalar doublet ($Φ_ν$), which couples exclusively with the heavy right-handed neutrinos and the lepton doublet, thereby forming the neutrino Dirac mass term, while the first doublet is responsible for the mass generation of the remaining Standard Model particles. The lightest sterile neutrino…
