متن کاملMeasurement of Dijet Production at Low Q2 at HERA
The measurement of triple differential dijet cross sections in e±p interactions in the H1 experiment in the region of photon virtualities 2 < Q < 80GeV, inelasticities 0.1 < y < 0.85, jet transverse energies E∗ T 1 > 7GeV, E ∗ T 2 > 5GeV, and pseudorapidities −2.5 < η∗ 1 , η∗ 2 < 0 is presented. The analysis was done in the γ∗p centre-of-mass frame using an integrated luminosity of 57.6 pb−1. T...
متن کاملMeasurement of the Proton Structure Function F2 at low Q2 in QED Compton Scattering at HERA
The proton structure function F2(x, Q2) is measured in inelastic QED Compton scattering using data collected with the H1 detector at HERA. QED Compton events are used to access the kinematic range of very low virtualities of the exchanged photon, Q2, down to 0.5 GeV2, and Bjorken x up to ∼0.06, a region which has not been covered previously by inclusive measurements at HERA. The results are in ...
متن کاملMeasurement of single and double radiative low-Q2 Bhabha scattering at Ec.m.
. The process e+e+ e+e-y(y), where one electron scatters at a small angle, is studied with data from the Mark11 detector at the PEP storage ring. The data are in excellent agreement with a Monte Carlo calculation and include a large contribution from order (u4. The ratio of measured to calculated cross sections is, R = 0.993 f 0.017 f 0.015, where the first error is statistical and the second s...
متن کاملNeutron Spin Sum Rules and Spin Polarizabilities at Low Q2
izabilities have been formed. These proceedings will concentrate on recent measurments on the neutron via a polarized 3He target in the low Q2 region. In particular, experiment E97-110 was performed in Hall A to study the neutron and 3He spin structure at four-momentum transfers between 0.02 and 0.3 GeV2. This Q2 range allows us to make a benchmark-check of Chiral Perturbation Theory calculatio...
