Measurement 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 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 AND QCD-ANALYSIS OF THE PROTON STRUCTURE FUNCTION F2(x;Q2) AT HERA
New results on measurements of the proton structure function F 2 (x;Q 2) from H1 and ZEUS at HERA are presented. The data were collected in 1995 and 1996 covering the range 0:16 Q 2 90 GeV 2 and reaching values of x down to 210 ?6. Contrary to observations at values of Q 2 10 GeV 2 , the rise in F 2 with decreasing x is found to be weaker at low Q 2. Conventional NLO QCD evolution equations pro...

متن کاملLow Q 2 – Intermediate x Structure Function Measurement at HERA
The result of a measurement of the proton structure function F 2 (x; Q 2) is reported in an extended kinematic domain at low Q 2 (Q 2 > 0:2 GeV 2) and intermediate Bjorken-x (x < 0:0032) using deep inelastic events with a photon radiation collinear to the incident electron, collected in 1996 by the HERA experiment H1. The rise of F 2 with decreasing x is found to be less steep towards low Q 2 v...
