We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 < or =Q2 =1.0 GeV2. These asymmetries, arising from interference electromagnetic and neutral weak interactions, are sensitive to strange-quark contributions currents proton. The measurements were made at Jefferson Laboratory using a toroidal spectrometer detect recoiling protons liquid hydrogen target. results indicate nonzero, Q2 dependent, provide new information...
The violation of mirror symmetry in the weak force provides a powerful tool to study internal structure proton. Experimental results have been obtained that address role strange quarks generating nuclear magnetism. measurement reported here an unambiguous constraint on quark contributions proton's magnetic moment through electron-proton interaction. We also report evidence for existence parity-violating electromagnetic effect known as anapole is not yet well understood theoretically, but it...
We report on a new measurement of the parity-violating asymmetry in quasielastic electron scattering from deuteron at backward angles Q2=0.038 (GeV/c)2. This quantity provides determination neutral weak axial vector form factor nucleon, which can potentially receive large electroweak corrections. The measured A=-3.51+/-0.57 (stat)+/-0.58 (syst) ppm is consistent with theoretical predictions. also updated results previous experiment Q2=0.091 (GeV/c)2, are
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q2=0.15, 0.25 (GeV/c)2. The results are inconsistent with calculations solely using nucleon intermediate state and generally agree significant inelastic hadronic contributions. A(n) provides a direct probe imaginary component 2gamma exchange amplitude, complete description which is important interpretation data precision electron-scattering experiments.
Virotherapy of cancer exploits the potential naturally occurring and engineered oncolytic viruses to selectively replicate in cause cytotoxicity tumor cells without affecting healthy normal cells. The selectivity Newcastle disease virus (NDV), a member family Paramyxoviridae, depends on differential type I interferon (IFN) response. Further understanding key mechanisms immune effector molecules involved will aid augmenting properties NDV. Here we report infection kinetics innate responses...
