The Jiangmen Underground Neutrino Observatory (JUNO) is proposed to determine the neutrino mass hierarchy using an underground liquid scintillator detector. It located 53 km away from both Yangjiang and Taishan Nuclear Power Plants in Guangdong, China. experimental hall, spanning more than 50 meters, under a granite mountain of over 700 m overburden. Within six years running, detection reactor antineutrinos can resolve at confidence level 3-4$\sigma$, oscillation parameters...
The LHCb has discovered two new states with preferred J P quantum numbers 3/2− and 5/2+ from Λ b decays. These can be interpreted as hidden charm pentaquarks. It been argued that the main features of these pentaquarks described by diquark model. model predicts are in separate octet multiplets flavor SU(3) there is also an additional decuplet pentaquark multiplet. Finding provide crucial evidence for this weak decays b-baryon to a light meson have Cabibbo allowed suppressed decay channels. We...
We report the results of a weakly interacting massive particle (WIMP) dark matter search using full 80.1 live-day exposure first stage PandaX experiment (PandaX-I) located in China Jin-Ping Underground Laboratory. The PandaX-I detector has been optimized for detecting low-mass WIMPs, achieving photon detection efficiency 9.6%. With fiducial liquid xenon target mass 54.0 kg, no significant excess events were found above expected background. A profile likelihood ratio analysis confirms our...
This study proposes a double-rough-walled fracture model to represent the natural geometries of rough fractures. The surface is generated using modified successive random additions (SRA) algorithm and aperture distribution during shearing calculated mechanistic model. shear-flow simulations are performed by directly solving Navier-Stokes (NS) equations. results show that can improve accuracy fluid flow approximately 14.99%–19.77%, compared with commonly used single-rough-walled ratio rate...
Abstract The ocean, as the Earth's largest yet underexploited energy reservoir, harbors immense potential for development. However, low‐frequency and low‐amplitude characteristics of oceanic waves pose significant limitations on harvesting efficiency electromagnetic generators. In contrast, advanced triboelectric nanogenerators exhibit distinct advantages in converting mechanical motion into electrical energy. This review systematically summarizes latest developments nanogenerator (TENG)...
A 2.25$\times10^8$ $\jpsi$ event sample accumulated with the BESIII detector is used to study doubly OZI suppressed decay modes $\jpsi\to\gamma\of$, $\omega\to\ppp$, $\phi\to\kk$. strong deviation ($>$ 30$\sigma$) from three-body $\jpsi\to\gamma\omega\phi$ phase space observed near $\omega\phi$ mass threshold that consistent a previous observation reported by BESII experiment. partial wave analysis tensor covariant amplitude assumes enhancement due presence of resonance, X(1810), performed,...
Several baryons containing a heavy b-quark, the b-baryons, have been discovered. The charmless two-body decays of b-baryons can provide new platform for $CP$ violating studies in similar way provided by B-meson. There are observables related to baryon polarization b-baryon decays. We show that flavor $SU(3)$ limit, there exists relations involving different combinations decay amplitudes compared with those rate asymmetry. These therefore interesting tests mechanism violations standard model...
Based on a sample of 225.3 million J/ψ events accumulated with the BESIII detector at BEPCII, decays η′→π+π−l+l− are studied via J/ψ→γη′. A clear η′ signal is observed in π+π−e+e− mass spectrum, and branching fraction measured to be B(η′→π+π−e+e−)=(2.11±0.12(stat)±0.14(syst))×10−3, which good agreement theoretical predictions previous measurement, but determined much higher precision. No found π+π−μ+μ− upper limit B(η′→π+π−μ+μ−)<2.9×10−5 90% confidence level.Received 29 March...
A coupling of a dark photon $A'$ from $U(1)_{A'}$ with the standard model (SM) particles can be generated through kinetic mixing represented by parameter $\epsilon$. non-zero $\epsilon$ also induces between and $Z$ if mass $m_{A'}$ is not zero. This large when close to $m_Z$ even small. Many efforts have been made constrain for low compared boson $m_Z$. We study search in $e^+e^- \to \gamma A' \mu^+ \mu^-$ as kinematically allowed at future $e^+e^-$ colliders. For $m_{A'}$, care should taken...
A new U(1)X gauge boson field X can have renormalizable kinetic mixing with the standard model (SM) U(1)Y Y. This induces interactions of SM particles even though starts as a dark photon without such interactions. If is not broken, both and are massless. One cannot determine which one them physical or by just looking at terms in Lagrangian. We revisit this issue show explicitly that when all contributions included, processes do depend on basis used effects up electromagnetic weak if only...

Recent data collected by ATLAS and CMS at 13 TeV collision energy of the LHC indicate existence a new resonant state $ϕ$ with mass 750 GeV decaying into two photons $γγ$. The properties should be studied further also future colliders. Since only $ϕ\to γγ$ decay channel has been measured, one best ways to extract more information about is use $γγ$ collider produce energy. In this work we show how helps verify provide some most important $ϕ$, such as branching fractions V_1V_2$. Here $V_i$ can...
One of the interesting portals linking a dark sector and standard model (SM) is kinetic mixing between SM $U(1)_Y$ field with new photon $A'$ from $U(1)_{A'}$ gauge interaction. Stringent limits have been obtained for parameter $\epsilon$ through various processes. In this work, we study possibility searching interaction at circular $e^+e^-$ collider process $e^+ e^-\to \gamma A^{\prime *} \to \mu^+\mu^-$. We find that constraint on $\epsilon^2$ mass in few tens GeV range, assuming...
