萨德伯里中微子天文台测量到的各种太阳中微子通量将非标准能量损失限制在太阳光子光度的10%以下,取代了日震学的论点,并对低质量粒子的相互作用强度提供了新的限制。对于轴子-光子耦合强度,我们发现g{sub a{gamma}}<7 × 10 {sup -10} GeV{sup -1}。我们还得到明确的限制Yukawa耦合到电子的赝标,标量和矢量玻色子与千电子伏规模的质量。
The all-flavor solar neutrino flux measured by the Sudbury Neutrino Observatory constrains nonstandard energy losses to less than about 10% of the Sun's photon luminosity, superseding a helioseismological argument and providing new limits on the interaction strength of low-mass particles. For the axion-photon coupling strength we find g{sub a{gamma}}<7x10{sup -10} GeV{sup -1}. We also derive explicit limits on the Yukawa coupling to electrons of pseudoscalar, scalar, and vector bosons with keV-scale masses.
