Strangeness Production at GlueX
Abstract
The GlueX experiment at Jefferson Lab is well suited for exclusive studies of strangeness production, combining a linearly polarized photon beam at 8.0 < Eγ< 8.8 GeV with a large-acceptance detector that reconstructs weakly decaying hyperons. We outline a research program built on three aspects: (i) spectroscopy of strange mesons, where many excited K* states remain unestablished and crypto-exotic strange hybrids must be identified from combined spectrum and decay information, anchored by the K*(892) as a standard candle; (ii) spin dynamics, where the first precise measurements of the complete spin-density matrix elements in the photoproduced K*(892)Λ system beyond the Schilling formalism constrain the t-channel strange production mechanism; and (iii) hadronization, probed through the newly published pp̅, ΛΛ̅, and pΛ̅ photoproduction cross sections and emerging ΛΛ̅ spin-correlation measurements. We place these efforts in the context of the broader GlueX strangeness program and give an outlook toward the high-statistics GlueX-II era.
