Search for compositeness, leptoquarks and large extra dimensions in e q contact interactions at hera
The reaction e+p --> e+X is studied with the H1 detector at Hera. The data cover momentum transfers Q^2 between 200 GeV^2 and 30,000 GeV^2 and correspond to an integrated luminosity of 35.6 pb^(-1). The differential cross section dsigma/dQ^2 is compared to the Standard Model expectation for neutr...

| description | The reaction e+p --> e+X is studied with the H1 detector at Hera. The data cover momentum transfers Q^2 between 200 GeV^2 and 30,000 GeV^2 and correspond to an integrated luminosity of 35.6 pb^(-1). The differential cross section dsigma/dQ^2 is compared to the Standard Model expectation for neutral current scattering and analysed to search for bar(e)e bar(q)q contact interactions. No evidence for new phenomena is observed. The results are used to set limits on scales within models of electron--quark compositeness, quark form factors and the exchange of virtual heavy leptoquarks. A search for gravitational effects mediated through the exchange of virtual gravitons which propagate into large extra dimensions is presented. |

The data cover momentum transfers Q^2 between 200 GeV^2 and 30,000 GeV^2 and correspond to an integrated luminosity of 35.6 pb^(-1). The differential cross section dsigma/dQ^2 is compared to the Standard Model expectation for neutral current scattering and analysed to search for bar(e)e bar(q)q contact interactions. No evidence for new phenomena is observed. The results are used to set limits on scales within models of electron--quark compositeness, quark form factors and the exchange of virtual heavy leptoquarks. A search for gravitational effects mediated through the exchange of virtual gravitons which propagate into large extra dimensions is presented.</abstract><pub>Elsevier</pub><orcidid>https://orcid.org/0000-0002-6473-0243</orcidid><orcidid>https://orcid.org/0000-0002-2837-2442</orcidid><orcidid>https://orcid.org/0000-0002-7031-7754</orcidid><orcidid>https://orcid.org/0000-0001-8164-5625</orcidid><orcidid>https://orcid.org/0000-0002-5230-8387</orcidid><orcidid>https://orcid.org/0000-0002-2011-0851</orcidid><orcidid>https://orcid.org/0000-0002-1258-1338</orcidid><orcidid>https://orcid.org/0000-0002-1367-9900</orcidid><orcidid>https://orcid.org/0000-0001-9238-2146</orcidid><orcidid>https://orcid.org/0000-0002-2837-2442</orcidid><orcidid>https://orcid.org/0000-0002-1367-9900</orcidid><orcidid>https://orcid.org/0000-0002-1258-1338</orcidid><orcidid>https://orcid.org/0000-0002-5230-8387</orcidid></addata></record> |
