A branch of high-frequency Alfvenic modes is observed on the HL-2A tokamak.The electromagnetic mode can be driven unstably in the plasma with an off-axis neutral beam heating.Its mode frequency keeps almost unchanged or presents a slow-sweeping behavior,depending on the detail current evolution.The poloidal and toroidal mode numbers arem=1/1.The mode has a quite short duration(≤20 ms)and usually appears 5-10 ms after the neutral beam being injected into the plasma.Hybrid simulations based on M3D-K have also been carried out.The result suggests that co-passing energetic particles are responsible for the mode excitation.The simulated mode structures are localized nearby location of minimum safety factor(q_min)and agree with the structures obtained through tomography of soft x-ray arrays.Further,the modes are localized in the continuum gap and their frequencies increase with variation ofmin in a wide range.Last but not least,the characteristic of unchanged frequency on experiment is also reproduced by the nonlinear simulation with a fixed safety factor.All those evidences indicate that then=1 high-frequency mode may belong to a reversed shear Alfven eigenmode. 展开更多

The kinetic effects of thermal particles and fast ions on internal kink(IK)mode are numerically investigated by the MHD-kinetic hybrid code MARS-K.It is shown that either thermal particles or fast ions have stabilizing influence on IK.However,the former can not fully stabilize IK,and the later can suppress the IK.In addition,the synergistic effect from thermal particles and fast ions induces more stronger damping on IK.The kinetic effects from particles significantly raise the critical value of poloidal beta(βpcrit)for driving IK in the toroidal plasma.This implies a method of controlling IK or sawtooth in the high-βp discharge scenario of tokamak.It is noted that,at the q=1 rational surface,mode structure becomes more sharp due to the self-consistent modification by particles’kinetic effect. 展开更多

By analyzingψ(3686)data sample containing(107.7±0.6)×10⁶events taken with the BESIII detector at the BEPCII storage ring in 2009,theχ_(c 0)resonance parameters are precisely measured usingχ_(c 0,c 2)→π⁺π⁻/K⁺K⁻events.The mass ofχ_(c 0)is determined to be M(χ_(c 0))=(3415.63±0.07±0.07±0.07)MeV/c²,and its full width is F(χ_(c 0))=(12.52±0.12±0.13)MeV,where the first uncertainty is statistical,the second systematic,and the third for mass comes fromχ_(c 2)mass uncertainty.These measurements improve the precision ofχ_(c 0)mass by a factor of four and width by one order of magnitude over the previous individual measurements,and significantly boost our knowledge about the charmonium spectrum.Together with additional(345.4±2.6)×10⁶(3686)data events taken in 2012,the decay branching fractions ofχ_(c 0,c 2)→π⁺π⁻/K⁺K⁻are measured as well,with precision improved by a factor of three compared to previous measurements.Theseχ_(c 0)decay branching fractions provide important inputs for the study of glueballs. 展开更多

Using 20.3 fb^-1of e⁺e^-annihilation data collected at a center-of-mass energy of 3.773 GeV with the BESⅢdetector,we report on an improved search for the radiative leptonic decay D⁺→γe⁺ve.An upper limit on its partial branching fraction for photon energies E_γ>10 MeV was determined to be 1.2×10^-5at a 90%confidence level;this excludes most current theoretical predictions.A sophisticated deep learning approach,which includes thorough validation and is based on the Transformer architecture,was implemented to efficiently distinguish the signal from massive backgrounds. 展开更多

Based on a sample of 2.7x 10⁹ψ(3686)events collected by the BESIII detector operating at the BEP-CII collider,the decay 4(3686)→YX_cJ,X_cJ→ηηη’is analyzed.The decay modes X_c1and X_c2→ηηη’are observed for the first time,and their corresponding branching fractions are determined to be B(X_c1→ηηη’)=(1.40±0.13(stat.)±0.09(sys.))×10^-4and B(X_c2→ηηη’)=(4.18±0.84(stat.)±0.48(sys.))×10^-5.An upper limit on the branching fraction of x_co→ηηη’is set as 2.59×10^-5at a 90%confidence level(CL).A partial wave analys-is(PWA)of the decay X_c1→ηηη’is performed to search for the 1^-+exotic stateη1(1855).The PWA result indic-ates that the structure in theηη’mass spectrum is attributed to f₀(1500),while in the m mass spectrum,it is attrib-uted to the 0⁺⁺phase space.The upper limit of B(x_cl→η1(1855)η)·B(η1(1855)→ηη')<9.79×10^-5is set based on the PWA at 90%CL. 展开更多

First evidence of a structure in the J/ψΛinvariant mass distribution is obtained from an amplitude analysis of■b^-J/ψΛK^-decays.The observed structure is consistent with being due to a charmonium pentaquark with strangeness with a significance of 3.1r including systematic uncertainties and lookelsewhere effect.Its mass and width are determined to be 4458:8±2:9t4:7-1:1 MeV and 17:3±6:5t8:0-5:7 MeV,respectively,where the quoted uncertainties are statistical and systematic.The structure is also consistent with being due to two resonances.In addition,the narrow excited■^-states,N■(1690)and■(1820),are seen for the first time in a■b^-decay,and their masses and widths are measured with improved precision.The analysis is performed using pp collision data corresponding to a total integrated luminosity of 9 fb^-1,collected with the LHCb experiment at centre-of-mass energies of 7,8 and 13 TeV. 展开更多

A search for the doubly charmed baryonΞcc+is performed through its decay to theΛc+K-π+final state,using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7,8 and 13 Te V.The data correspond to a total integrated luminosity of 9 fb-1.No significant signal is observed in the mass range from 3.4 to 3.8 Ge V/c2.Upper limits are set at 95%credibility level on the ratio of theΞcc+production cross-section times the branching fraction to that ofΛc+andΞcc++baryons.The limits are determined as functions of theΞcc+mass for different lifetime hypotheses,in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c. 展开更多

A first search for theΞ_bc⁺J/ψΞ_c⁺decay is performed by the LHCb experiment with a data sample of proton-proton collisions,corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7,8,and 13 TeV.Two peaking structures are seen with a local(global)significance of 4.3(2.8)and 4.1(2.4)standard deviations at masses of 6571 and 6694 MeV/c2,respectively.Upper limits are set on theΞ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 TeV,in theΞ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20GeV/c,respectively.Upper limits are presented as a function of theΞ+bc mass and lifetime. 展开更多

The production ofΞcc++baryons in proton-proton collisions at a centre-of-mass energy of s1/2=13 TeV is measured in the transverse-momentum range 4<pT<15 GeV/c and the rapidity range 2.0<y<4.5.The data used in this measurement correspond to an integrated luminosity of 1.7 fb-1,recorded by the LHCb experiment during2016.The ratio of theΞcc++production cross-section times the branching fraction of theΞcc++→Λc+K-π+π+decay relative to the promptΛc+production cross-section is found to be(2.22±0.27±0.29)×10-4,assuming the central value of the measuredΞcc++lifetime,where the first uncertainty is statistical and the second systematic. 展开更多

A search for the rare decays W⁺→D_s⁺γand Z→D0γis performed using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of 13TeV,corresponding to an integrated luminosity of 2.0fb−1.No significant signal is observed for either decay mode and upper limits on their branching fractions are set using W⁺→D_s⁺γand Z→μ+μ−decays as normalization channels.The upper limits are 6.5×10⁻⁴and 2.1×10⁻³at 95%confidence level for the W⁺→D_s⁺γand Z→D⁰γdecay modes,respectively.This is the first reported search for the Z→D⁰γdecay,while the upper limit on the W+→D+sγbranching fraction improves upon the previous best limit. 展开更多

The first search for the doubly heavyΩ⁰_bcbaryon and a search for the E⁰_bcbaryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^-1.The baryons are reconstructed via their decays toΛ⁺_cπ^-and E⁺_cπ^-.No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c²,in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/c.Upper limits are set on the ratio of theΩ⁰_bcand E⁰_bcproduction cross-section times the branching fraction toΛ⁺_cπ^-(E⁺_cπ^-)relative to that of theΛ⁰_b(E⁰_b)baryon,for different lifetime hypotheses,at 95%confidence level.The upper limits range from 0.5 x 10^-4to 2.5 x 10^-4for theΩ⁰_bc→Λ⁺_cπ^-(E⁰_bc→Λ⁺_cπ^-)decay,and from 1.4x 10^-3to 6.9 x 10^-3for theΩ⁰_bc→E⁺_cπ^-(E⁰_bc→E⁺_cπ^-)decay,depending on the considered mass and lifetime of theΩ⁰_bc(E⁰_bc)baryon. 展开更多
