Creep Behavior of Internally Cured UHPC with Calcined Bauxite Aggregate or Lightweight Aggregate

Yalin Liu, Ya Wei, Wei He, Tianyong Huang et autres

The creep property of ultrahigh-performance concrete (UHPC) is important for long-term performance and safe design of UHPC structures, such as large-span prestressed UHPC bridges. A strong and porous aggregate [calcined bauxite (CB)] has been applied as novel internal curing agent to mitigate …

Search for a $1^{-+}$ molecular state via $e^{+}e^{-} \to γD^{+}_{s} D_{s1}^{-}(2536) +c.c.$

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

We search, for the first time, for an exotic molecular state with quantum numbers $J^{PC}=1^{-+}$, called $X$, via the process $e^{+}e^{-} \to γD^{+}_{s} D_{s1}^{-}(2536) +c.c.$ using data samples corresponding to a luminosity of $5.8~\mathrm{fb^{-1}}$ across center-of-mass energies from 4.612 to 4.951~GeV, collected …

A state-of-the-art review of research on the use of calcined bauxite aggregate in civil engineering

Yalin Liu, C. H. Li, Ya Wei, Linbing Wang

Calcined bauxite (CB) aggregate is characterized by high strength, hardness, and high abrasion resistance. It has promising application value in the field of civil engineering with special functional needs. This study describes in detail the macroscopic and microscopic properties of CB aggregates, …

Observation of the $Y(4230)$ and evidence for a new vector charmonium-like state $Y(4710)$ in $e^{+}e^{-}\to K_{S}^{0} K_{S}^{0} J/ψ$

М. Н. Ачасов, P. Adlarson, M. Albrecht, R. Aliberti et autres

Cross sections for the process $e^{+} e^{-} \to K_{S}^{0} K_{S}^{0} J/ψ$ at center-of-mass energies from $4.128$ to $4.950$ GeV are measured using data samples with a total integrated luminosity of 21.2 fb$^{-1}$ collected by the BESIII detector operating at the BEPCII storage …

Observation of a state $X(2600)$ in the $π^{+}π^{-}η'$ system in the process $J/ψ\rightarrowγπ^{+}π^{-}η'$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Based on $(10087\pm44)\times10^{6}$ $J/ψ$ events collected with the BESIII detector, the process $J/ψ\rightarrowγπ^{+}π^{-}η'$ is studied using two dominant decay channels of the $η'$ meson, $η'\rightarrowγπ^{+}π^{-}$ and $η'\rightarrowηπ^{+}π^{-},η\rightarrowγγ$. The $X(2600)$ is observed with a statistical significance larger than 20$σ$ in the $π^{+}π^{-}η'$ invariant …

Observation of the $ψ(1^3D_2)$ state in $e^+e^-\toπ^+π^-γχ_{c1}$ at BESIII

М. Н. Ачасов, X. Ai, O. Albayrak, M. Albrecht et autres

We report the observation of the $X(3823)$ in the process $e^+e^-\to π^+π^-X(3823) \to π^+π^-γχ_{c1}$ with a statistical significance of $6.2σ$, in data samples at center-of-mass energies $\sqrt{s}=$4.230, 4.260, 4.360, 4.420 and 4.600~GeV collected with the BESIII detector at the BEPCII electron positron …
