Electro-Strong Interaction and High Q Events at HERA

نویسنده

چکیده

A previously proposed unified field theory of electro-strong interactions requires two scales of length within hadrons, ∼ 10m and ∼ 10m respectively, and the onset of new phenomena at the shorter scale. Studies at the HERA electron-proton collider at the shorter scale have revealed a possible excess of high-transverse momentum events, as expected, with Q ≥ 30, 000 (Gev/c). The collider is currently being upgraded. This will permit a clearer test to be carried out.

Contact Interactions and High-q 2 Events in E + P Collisions at Hera

We consider eeqq contact interactions as a possible origin of an excess of events above Standard Model predictions in e + p ! e + jet at high Q 2 observed by the H1 and ZEUS collaborations at HERA. The HERA data prefer chirality RL or LR contact terms and atomic physics parity violation measurements severely limit parity-odd contact terms. With equal left-right and right-left chirality interact...

We discuss the polarized proton-positron scattering in the context of the excess of high-Q 2 events at HERA. We define and estimate a polarized asymmetry to examine the two scenarios, the contact interaction and stop scenario without R-parity. This asymmetry shows a characteristic behavior depending on the scenarios. Thus the polarized experiment at HERA will provide with a good test for these ...

Effective eeqq contact interactions can enhance event rates in ep scattering at HERA at high Q. Present constraints from atomic parity violation measurements and from Drell Yan events at the Tevatron are discussed. Both the H1 [1] and ZEUS [2] experiments at HERA have observed an excess above SM expectations in ep → ejX events at Q > 15,000 GeV. Only the H1 data, however, are suggestive of an s...

Could we learn more about HERA high Q 2 anomaly from LEP 200 and TEVATRON ? R - parity violation scenario

The excess of high Q 2 events at HERA reported in the early 1997 by H1 and ZEUS collaborations has become the subject of extensive studies in the framework of several models related to new physics. Here we concentrate on the most promising , from our point of view, model describing HERA anomaly. We update our previous analysis [3] and take into account new HERA statistics of the 1997 year. HERA...
