SUMMARY:Measuring the nucleon axial form factor in deuterium and hydro
 gen can’t be that hard?\, High Energy Seminar\, Rik Gran\, Professor
  Physics and Astronomy University of Minnesota Duluth\,  Co-spokespers
 on MINERvA experiment
DESCRIPTION:In a recent paper in Nature\, the MINERvA neutrino cross s
 ection experiment presented a measurement of the axial form factor of 
 the nucleon using anti-neutrino reactions on protons (hydrogen nuclei)
 .   This is the first new nucleon data since the 1980’s bubble chamb
 er measurements that used neutrino + neutron (in deuterium) reactions.
   Phenomenological nucleon form factors are essential information for 
 two customers.  They are used in the calculation of the baseline event
  rates for neutrino + nucleus interactions used in the search of other
  phenomena\, such as neutrino oscillation parameters and CP violation.
    They can also be calculated using QCD lattice techniques\, where ca
 lculations may in principle be more precise than the existing measurem
 ents.   This talk will split between celebrating the 50 year history o
 f the deuterium measurements and describing the new MINERvA measuremen
 t\, with implications for current and upcoming neutrino experiments su
 ch as T2K\, NOvA\, SBN\, and DUNE.
