The EIC Comprehensive Chromodynamics Experiment (ECCE) detector has been designed to address the full scope of the proposed Electron Ion Collider (EIC) physics program as presented by the National Academy of Science and provide a deeper understanding of the quark–gluon structure of matter. To accomplish this, the ECCE detector offers nearly acceptance and energy coverage along with excellent tracking and particle identification. The ECCE detector was designed to be built within the budget envelope set out by the EIC project while simultaneously managing cost and schedule risks. This detector concept has been selected to be the basis for the EIC project detector.

First Determination of the Spin-Parity of $Ξ_{c} (3055)^{+, 0}$ Baryons

https://doi.org/10.1103/PhysRevLett.134.081901

The $Ξ_{b}^{0 (-)} \to Ξ_{c} (3055)^{+ (0)} (\to D^{+ (0)} Λ) π^{-}$ decay chains are observed, and the spin-parity of $Ξ_{c} (3055)^{+ (0)}$ baryons is determined for the first time. The measurement is performed using proton-proton collision data at a center-of-mass energy of $\sqrt{s} = 13 TeV$ , corresponding to an integrated luminosity of $5.4 {fb}^{- 1}$ , recorded by the LHCb experiment between 2016 and 2018. The spin-parity of the $Ξ_{c} (3055)^{+ (0)}$ baryons is determined to be $3 / 2^{+}$ with a significance of more than $6.5 σ$ ( $3.5 σ$ ) compared to all other tested hypotheses. The up-down asymmetries of the $Ξ_{b}^{0 (-)} \to Ξ_{c} (3055)^{+ (0)} π^{-}$ transitions are measured to be $- 0.92 \pm 0.10 \pm 0.05$ ( $- 0.92 \pm 0.16 \pm 0.22$ ), consistent with maximal parity violation, where the first uncertainty is statistical and the second is systematic. These results support the hypothesis that the $Ξ_{c} (3055)^{+ (0)}$ baryons correspond to the first $D$ -wave $λ$ -mode excitation of the $Ξ_{c}$ flavor triplet. © 2025 CERN, for the LHCb Collaboration2025CERN

Measurement of $C P$ Violation Observables in $D^{+} \to K^{-} K^{+} π^{+}$ Decays

https://doi.org/10.1103/PhysRevLett.133.251801

Aaij, R; Abdelmotteleb, A_S W; Abellan_Beteta, C; Abudinén, F; Ackernley, T; Adefisoye, A A; Adeva, B; Adinolfi, M; Adlarson, P; Agapopoulou, C; et al (December 2024, Physical Review Letters)

A search for violation of the charge-parity ( $C P$ ) symmetry in the $D^{+} \to K^{-} K^{+} π^{+}$ decay is presented, with proton-proton collision data corresponding to an integrated luminosity of $5.4 {fb}^{- 1}$ , collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the $D^{+}$ and $D^{-}$ phase-space distributions, with instrumental asymmetries subtracted using the $D_{s}^{+} \to K^{-} K^{+} π^{+}$ decay as a control channel. The $p$ value for the hypothesis of $C P$ conservation is 8.1%. The $C P$ asymmetry observables $A_{C P | S}^{ϕ π^{+}} = (0.95 \pm 0.4 3_{stat} \pm 0.2 6_{syst}) \times 10^{- 3}$ and $A_{C P | S}^{{\bar{K}}^{* 0} K^{+}} = (- 0.26 \pm 0.5 6_{stat} \pm 0.1 8_{syst}) \times 10^{- 3}$ are also measured. These results show no evidence of $C P$ violation and represent the most sensitive search performed through the phase space of a multibody decay. © 2024 CERN, for the LHCb Collaboration2024CERN

Measurement of $Λ_{b}^{0}$ , $Λ_{c}^{+}$ , and $Λ$ Decay Parameters Using $Λ_{b}^{0} \to Λ_{c}^{+} h^{-}$ Decays

https://doi.org/10.1103/PhysRevLett.133.261804

Aaij, R; Abdelmotteleb, A_S W; Abellan_Beteta, C; Abudinén, F; Ackernley, T; Adefisoye, A A; Adeva, B; Adinolfi, M; Adlarson, P; Agapopoulou, C; et al (December 2024, Physical Review Letters)

A comprehensive study of the angular distributions in the bottom-baryon decays $Λ_{b}^{0} \to Λ_{c}^{+} h^{-} (h = π, K)$ , followed by $Λ_{c}^{+} \to Λ h^{+}$ with $Λ \to p π^{-}$ or $Λ_{c}^{+} \to p K_{S}^{0}$ decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of $9 {fb}^{- 1}$ collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity ( $C P$ ) asymmetries are measured, with no significant $C P$ violation observed. For the first time, the $Λ_{b}^{0} \to Λ_{c}^{+} h^{-}$ decay parameters are measured. The most precise measurements of the decay parameters $α$ , $β$ , and $γ$ are obtained for $Λ_{c}^{+}$ decays and an independent measurement of the decay parameters for the strange-baryon $Λ$ decay is provided. The results deepen our understanding of weak decay dynamics in baryon decays. © 2024 CERN, for the LHCb Collaboration2024CERN
