Nucleon Spin and Momentum Decomposition Using Lattice QCD Simulations

Nucleon Spin and Momentum Decomposition Using Lattice QCD Simulations | Nuclear Physics | Scoop.it
We determine within lattice QCD the nucleon spin carried by valence and sea quarks and gluons. The calculation is performed using an ensemble of gauge configurations with two degenerate light quarks with mass fixed to approximately reproduce the physical pion mass. We find that the total angular momentum carried by the quarks in the nucleon is ${J}_{u+d+s}=0.408(61{)}_{\text{stat}}(48{)}_{\text{syst}}$ and the gluon contribution is ${J}_{g}=0.133(11{)}_{\text{stat}}(14{)}_{\text{syst}}$, giving a total of ${J}_{N}=0.54(6{)}_{\text{stat}}(5{)}_{\text{syst}}$ that is consistent with the spin sum. For the quark intrinsic spin contribution, we obtain $\frac{1}{2}\mathrm{\ensuremath{\Delta}}{\mathrm{\ensuremath{\Sigma}}}_{u+d+s}=0.201(17{)}_{\text{stat}}(5{)}_{\text{syst}}$. All quantities are given in the modified minimal subtraction scheme at 2 GeV. The quark and gluon momentum fractions are also computed and add up to $⟨x{⟩}_{u+d+s}+⟨x{⟩}_{g}=0.804(121{)}_{\text{stat}}(95{)}_{\text{syst}}+0.267(12{)}_{\text{stat}}(10{)}_{\text{syst}}=1.07(12{)}_{\text{stat}}(10{)}_{\text{syst}}$, thus satisfying the momentum sum.

A parts-per-billion measurement of the antiproton magnetic moment

A parts-per-billion measurement of the antiproton magnetic moment | Nuclear Physics | Scoop.it
Precise comparisons of the fundamental properties of matter–antimatter conjugates provide sensitive tests of charge–parity–time (CPT) invariance, which is an important symmetry that rests on basic assumptions of the standard model of particle physics. Experiments on mesons, leptons and baryons have compared different properties of matter–antimatter conjugates with fractional uncertainties at the parts-per-billion level or better. One specific quantity, however, has so far only been known to a fractional uncertainty at the parts-per-million level: the magnetic moment of the antiproton, nature24048-m1gif1K2318. The extraordinary difficulty in measuring nature24048-m2gif1K2318 with high precision is caused by its intrinsic smallness; for example, it is 660 times smaller than the magnetic moment of the positron. Here we report a high-precision measurement of nature24048-m3gif1K2318 in units of the nuclear magneton μN with a fractional precision of 1.5 parts per billion (68% confidence level). We use a two-particle spectroscopy method in an advanced cryogenic multi-Penning trap system. Our result nature24048-m4gif1K2318 = −2.7928473441(42)μN (where the number in parentheses represents the 68% confidence interval on the last digits of the value) improves the precision of the previous best nature24048-m5gif1K2318 measurement by a factor of approximately 350. The measured value is consistent with the proton magnetic moment, μp = 2.792847350(9)μN, and is in agreement with CPT invariance. Consequently, this measurement constrains the magnitude of certain CPT-violating effects to below 1.8 × 10−24 gigaelectronvolts, and a possible splitting of the proton–antiproton magnetic moments by CPT-odd dimension-five interactions to below 6 × 10−12 Bohr magnetons.
