摘要
极弱的新力可能导致对等效原理的明显违背。MICROSCOPE 实验意味着，与引力相比，新的长程力的相对强度在 2 σ 2\sigma 2 σ B , L , B − L , B + L B,\ L,\ B-L,\ B+L B , L , B − L , B + L 3 B + L 3B+L 3 B + L ∣ α ˉ g ∣ < 3.2 10 − 11 , 2.3 10 − 13 , 2.2 10 − 13 , 6.7 10 − 13 |\bar\alpha_g|<3.2\ 10^{-11},2.3\ 10^{-13},2.2\ 10^{-13},6.7\ 10^{-13} ∣ α ˉ g ∣ < 3.2 1 0 − 11 , 2.3 1 0 − 13 , 2.2 1 0 − 13 , 6.7 1 0 − 13 1.5 10 − 12 1.5\ 10^{-12} 1.5 1 0 − 12 ∣ α g ∣ < 8.4 10 − 12 |\alpha_g|<8.4\ 10^{-12} ∣ α g ∣ < 8.4 1 0 − 12 B B B ≃ 3 \simeq 3 ≃ 3 B − L B-L B − L α ˉ g \bar\alpha_g α ˉ g L L L B − L B-L B − L α g \alpha_g α g α ˉ g = α g / 4 \bar\alpha_g=\alpha_g/4 α ˉ g = α g /4 Q ˉ = B , 2 L , 2 ( B − L ) , 2 ( B + L ) / 3 \bar Q =B,\ 2L,\ 2(B-L),2(B+L)/3 Q ˉ = B , 2 L , 2 ( B − L ) , 2 ( B + L ) /3 2 ( 3 B + L ) / 7 2(3B+L)/7 2 ( 3 B + L ) /7 α ˉ g = α g × ( 1 , 1 / 4 , 1 / 4 , 9 / 4 \bar\alpha_g=\alpha_g\times(1,1/4,1/4,9/4 α ˉ g = α g × ( 1 , 1/4 , 1/4 , 9/4 49 / 4 ) 49/4) 49/4 ) L L L B − L B-L B − L B B B Δ ( 2 L / A r ) ≃ 144 Δ ( B / A r ) \Delta (2L/A_r)\simeq 144\ \Delta (B/A_r) Δ ( 2 L / A r ) ≃ 144 Δ ( B / A r ) B + L B+L B + L 3 B + L 3B+L 3 B + L ( ϵ B B + ϵ Q e l Q e l ) e (\epsilon_BB+\epsilon_{Q_{el}}Q_{el})e ( ϵ B B + ϵ Q e l Q e l ) e ∣ ϵ B ∣ < 5 10 − 24 |\epsilon_B|<5\ 10^{-24} ∣ ϵ B ∣ < 5 1 0 − 24 ∣ ϵ L ∣ |\epsilon_L| ∣ ϵ L ∣ ∣ ϵ B − L ∣ < .9 10 − 24 |\epsilon_{B-L}|<.9\ 10^{-24} ∣ ϵ B − L ∣ < .9 1 0 − 24 ∣ ϵ B + L ∣ < .5 10 − 24 , ∣ ϵ 3 B + L ∣ < .32 10 − 24 |\epsilon_{B+L}|<.5\ 10^{-24},|\epsilon_{3B+L}|<.32\ 10^{-24} ∣ ϵ B + L ∣ < .5 1 0 − 24 , ∣ ϵ 3 B + L ∣ < .32 1 0 − 24 ∣ ϵ B − 2 L ∣ < 2.6 10 − 24 |\epsilon_{B-2L}|<2.6\ 10^{-24} ∣ ϵ B − 2 L ∣ < 2.6 1 0 − 24 10 46 10^{46} 1 0 46 10 48 10^{48} 1 0 48 > 10 24 >10^{24} > 1 0 24 > 10 12 >10^{12} > 1 0 12 ξ ≈ 10 16 \sqrt\xi\approx 10^{16} ξ ≈ 1 0 16
