Pushing the limits of pulse shape discrimination in a large liquid xenon detector

D. S. Akerib, A. K. Al Musalhi, F. Alder, B. J. Almquist et autres

Abstract The LUX-ZEPLIN (LZ) experiment is a direct-detection dark matter experiment, optimized to search for weakly interacting massive particles (WIMPs) through WIMP-nucleon interactions. The main challenge in dark matter detection is differentiating between WIMP signals and background events. In LZ, the ratio …

First energy scan measurement of $e^{+}e^{-}\to K^{+}K^{-}$ around the $ψ(2S)$ resonance

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

We report the precise energy scan measurement of the cross section lineshape of $ψ(2S)\to K^{+}K^{-}$. The analysis is based on $e^{+}e^{-}$ collision data corresponding to an integrated luminosity of 495~pb$^{-1}$ collected with the BESIII detector at BEPCII. By analyzing the cross section …

Superlinear Temperature-Dependent Resistivity and Structural Phase Transition in BaNi$_2$P$_4$

E. H. Krenkel, M. A. Tanatar, E. I. Timmons, S. L. Bud'ko et autres

The mechanism of anomalous superlinear temperature-dependent resistivity, $ρ(T)$, in the metallic unconventional clathrate BaNi$_2$P$_4$ was studied by examining its evolution with artificial disorder induced by low-temperature ($\sim$ 20 K) 2.5 MeV electron irradiation. We find a dominant effect of the tetragonal-orthorhombic transition …

Measurement of CP asymmetries in $\kern 0.18em\overline{\kern -0.18em B}^0 \to D_s^- D^+$ and $\kern 0.18em\overline{\kern -0.18em B}_s^0 \to D_s^+ D^-$ decays

LHCb Collaboration, R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta et autres

Measurements of the combined CP asymmetries in $\kern 0.18em\overline{\kern -0.18em B}^0 \to D_s^- D^+$ and $\kern 0.18em\overline{\kern -0.18em B}_s^0 \to D_s^+ D^-$ decays are made using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9fb$^{-1}$. The …

Observation of $Λ^+_c\to nπ^+η$ and search for $Λ^+_c\to na_0(980)^+$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

By analysing 6.1 ${\rm fb}^{-1}$ of data collected at center-of-mass energies between $\sqrt{s}=4.600$ and 4.843 $\rm GeV$ with the BESIII detector at the BEPCII collider, we observe the decay $Λ_c^+\to nπ^+η$ for the first time with a statistical significance of $9.5σ$. The …

Observation of the doubly charmed baryon $\itΞ_{cc}^+$ with the LHCb Run 3 detector

LHCb Collaboration, R. Aaij, M. Abdelfatah, A. S. W. Abdelmotteleb et autres

The first observation of the doubly charmed baryon $\itΞ_{cc}^+$ is reported through its decay to the $\itΛ_c^+ K^-π^+$ final state, with a statistical significance exceeding seven standard deviations. The observation is made using proton-proton collision data collected in 2024 with the LHCb …

Optimal design of aluminium axial compression member with square hollow sections through a practical method

W Su, J. P. Wang, H. Wu, J. F. Hu

Aluminium columns are generally designed with hollow cross-sectional and thin-walled shapes to resist overall buckling under axial compression. Moreover, internal stiffeners are often added to column walls to improve local buckling resistance. However, only a few studies have been conducted to determine …
