The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose underground liquid scintillator detector, was proposed with the determination of neutrino mass hierarchy as primary physics goal. It is also capable observing neutrinos from terrestrial and extra-terrestrial sources, including supernova burst neutrinos, diffuse background, geoneutrinos, atmospheric solar well exotic searches such nucleon decays, dark matter, sterile etc. We present motivations anticipated...
The most efficient axion production mechanism in a supernova (SN) core is the nucleon-nucleon bremsstrahlung. This process has been often modeled at level of vacuum one-pion exchange (OPE) approximation. Starting from this naive recipe, we revise calculation including systematically different effects, namely non-vanishing mass for exchanged pion, contribution two-pions exchange, effective in-medium nucleon masses and multiple scatterings. Moreover, allow an arbitrary degree degeneracy. A...
We estimate the long-lasting gravitational wave (GW) emission of compact dark objects following a binary neutron-star (NS) merger. consider objects, which initially reside in centers NSs and may consist self-interacting matter (DM). By approximating as test particles, we model merging NS binaries hosting DM components with three-dimensional relativistic simulations. Our simulation results suggest that remain gravitationally bound orbit inside merger remnant orbital separations typically few...
The fixation of surfactants is very important in surfactant-promoted gas hydrate formation. In this work, three were fixed on the surface polystyrene nanospheres through emulsion polymerization (named as Surfactant@PSNS) and then used methane formation dissociation, which sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), alcohol ethoxylates (AEO). could reduce induction periods improve apparent densities storage capacities formed hydrates, especially at low surfactant...
We investigate the impact of charged-current--neutrino processes on formation and evolution neutrino spectra during deleptonization proto-neutron stars. To this end we develop full kinematics these reaction rates consistent with nuclear equation state, including weak magnetism contributions. This allows us to systematically study inelastic contributions ${\ensuremath{\nu}}_{e}$ ${\overline{\ensuremath{\nu}}}_{e}$ luminosities average energies. Furthermore, explore role inverse neutron decay,...
Sodium dodecyl sulfate (SDS) has been reported as the most efficient kinetic promoter for hydrate-based natural gas storage and transportation; however, foam generation during hydrate dissociation is a serious problem. In this work, we grafted −SO3– group (similar hydrophilic of SDS) on nanosheets graphene oxide (GO) to prepare −SO3–-coated GO (sulfonate oxide, SGO), which were then used promote methane formation. For comparison, (GP) also prepared promoters Among SGO, GP, GO, SGO produced...
The steady advance in core-collapse supernova simulations requires a more precise description of neutrino processes hot and dense matter. In this work, we study the rates charged-current (CC) weak with (anti)muons At relativistic mean field level, derive results for CC neutrino-nucleon reactions, taking into account full kinematics, magnetism pseudoscalar terms, $q^2$-dependent nucleon form factors hadronic current. addition to muonic semileptonic also consider purely leptonic processes....
We revisit the signatures from collisions of cosmic-rays on sub-GeV dark matter (DM) in Milky Way. In addition to upscattered DM component that can be probed by existing and neutrino experiments widely discussed, we examine associated signals $\gamma$-rays neutrinos span a wide energy range due inelastic scatterings. Assuming simple vector portal model for illustration, compute both flux cosmic-ray protons, resulting emission secondary high-energy proton excitation, hadronization, subsequent...
The present article investigates the impact of muons on core-collapse supernovae, with particular focus early muon neutrino emission. While presence is well understood in context neutron stars, until recent study by Bollig et al. [Phys. Rev. Lett. 119, 242702 (2017) role supernovae had been neglected---electrons and neutrinos were only leptons considered. In their study, disentangled tau antineutrinos included a variety muonic weak reactions, all which paper follows closely. Only then does...
Despite being a good promoter for methane hydrate formation, carbon nanotubes (CNTs) aggregate easily, which weakens their promotion effect. In this work, highly dispersed were prepared by coating the nanotube surface with an amphiphilic copolymer, namely, poly(styrene-co-sodium styrenesulfonate) (PSCS), to accelerate formation. presence of functionalized CNTs (f-CNTs), storage capacity increased from 46 ± 8 138 v/v when PSCS/CNT mass ratio (R) was 0 20. addition, formation period gradually...
Gas hydrate growth pattern is of great importance in hydrate-based gas storage and transportation. In this work, direction controlled methane the presence sodium dodecyl sulfate (SDS) was achieved through hydrophobic modification to surface design existing manner reaction solution reactor. Upward obtained when formation took place on hydrophilic surface, while hydrophobically modified, upward retarded. Downward accomplished by fixing middle part reactor, because both gravity capillary effect...
A comparative study on the synergistic effect of total ionizing dose and neutron single event a SiC MOSFET Si was performed based 60Co γ source high-pressure multiplier 14 MeV at China Institute Atomic Energy. First, γ-ray experiment these two devices, differences in damage MOSFETs were analyzed. Then, experiments to investigate effects different doses for devices. The results indicate that unhardened has stronger resistance compared with hardened MOSFET. During irradiation experiment, no...
The –SO<sub>3</sub><sup>−</sup>-coated nano-promoters resulted in methane hydrate formation process completing within 1–2 h, and displayed storage capacity over 140 v/v.
The direct detection of particle dark matter through its scattering with nucleons is fundamental importance to understand the nature DM. In this work, we propose that high-energy neutrino detectors like IceCube can be used uniquely probe DM-nucleon cross-section for DM $\sim$ PeV, up-scattered by cosmic rays. We derive first time strong constraints on down $\sim 10^{-32}$ cm$^2$ at energy scale sub-GeV candidates. Such independent far exceeding other existing experiments therefore provide...
Ag&–SO<sub>3</sub><sup>−</sup>-coated nano-promoters facilitated methane hydrate formation, which was complete within 1 h with the storage capacity reaching about 150 v/v.
We examine the constraints on sub-GeV dark sector particles set by proto-neutron star cooling associated with core-collapse supernova event SN1987a. Considering explicitly a photon portal model, we compute relevant interaction rates of ($A'$) and fermion ($\chi$) Standard Model as well their self-interaction inside sector. find that even small fine structure constant $\alpha_D\ll 1$, self-interactions can easily lead to own self-trapping. This effect strongly limits energy luminosity carried...
