Description
The new sPHENIX collider detector experiment features a unique tracking system capable of streaming readout, enabling the collection of very large, unbiased p+p datasets previously not available at RHIC. In two running periods during 2024 and 2025, sPHENIX collected over 14pb$^{-1}$ of unbiased pp collisions using the novel streaming readout capabilities of the tracking subsystems. This enables precise measurements of a wide variety of strange light and heavy flavor hadrons that can yield insight on hadron formation. In particular these measurements are sensitive to effects from color reconnection, hadronization mechanisms, and co-movers. This talk will present progress towards measurements at RHIC of strange and heavy flavor hadron ratios in p+p collisions, highlighting the unique capabilities enabled by streaming readout data collection.
