Measurements at high Q2 and searches at the ep energy frontier

A brief overview is given on most recent, preliminary results obtained by the HERA experiments H1 and ZEUS on the measurements of the neutral current (ep→eX) and charged current (ep→νX) deep inelastic scattering (DIS) cross sections at high values of negative four-momentum transfer squared, Q2. Such processes provide the possibility to study the structure of the proton, the dynamics of strong interactions, to test quantum chromodynamics (QCD) and also provide complementary information on the QCD and electroweak parts of the Standard Model (SM). In addition, a short report is given on indirect searches for new phenomena in which no evidence for the new physics has been found. The results presented in this paper are based on the full statistics of data collected at HERA, the only e±p collider, operated in the years 1992-2007 at centre-of-mass energies 300-320 GeV.
