  1. 51. Electroweak and Beyond the Standard Model Physics at the EIC
    Prof. Krishna Kumar (Stony Brook University)
    09/09/2015, 09:00
    Spin and 3-d structure
    Oral Presentation
    The EIC will reach new frontiers in accessible center-of-mass energies and polarized luminosity. These characteristics, coupled with the event topologies in collider mode, will allow exceptionally clean and precise measurements of neutral current amplitudes over a wide range of Q2 for the first time. In this talk, we discuss the new observables that would become accessible and the resulting...

  2. 87. Precision measurement of the weak mixing angle at MESA

    Beyond the Standard Model
    Oral Presentation
    MESA, the Mainz Energy-Recovering Superconducting Accelerator, will offer the possibility to measure the scattering of polarized electrons off protons at small energies (E=155 MeV) with very high precision.The parity-violating polarization asymmetry is determined by the weak charge of the proton and offers the possibility to measure the weak mixing angle with a relative precision of...

  3. 85. The neutrino-nucleon cross section at UHE and its astrophysical implications

    Beyond the Standard Model
    Oral Presentation
    We present a quantitative study of the νN cross section in the neutrino energy range 10^4< E_ν < 10^14 GeV within two transversal QCD approaches: NLO DGLAP evolution using different sets of PDFs and BK small-x evolution with running coupling and kinematical corrections. We show that the non-linear effects embodied in the BK equation yield a slower raise in the cross section for E_ν>10^8...

  4. 97. Proton radius puzzle: the status

    Beyond the Standard Model
    Oral Presentation
    Recent measurements of the Lamb shift in muonic hydrogen led to an extracted value of the proton charge radius $R^p_{\mu H}=0.84087(39)$ deviating from that obtained with a combined electronic hydrogen spectrum and electron scattering $R^p_{eH,\,e-scatt.}=0.8775(51)$ by 7 standard deviations. This discrepancy was coined "the proton radius puzzle" and has attracted much interest both on the...
