 2018-02-2114:04 [PUBDB-2018-01275] Report/Journal Article Malyshev, M. A. Possible small- x effects in the Kaluza-Klein graviton and radion production at high energies [DESY-17-038; arXiv:1612.03811] Physical review / D 95(9), 094010 (2017) [10.1103/PhysRevD.95.094010]   We study the single graviton production at the CERN LHC using the kT-factorization approach of QCD. We consider the Arkani-Hamed-Dimopoulos-Dvali scenario and Randall-Sundrum model with one warped extra dimension and derive the production amplitudes for spin-2 (Kaluza-Klein excitation of the graviton) and spin-0 (radion) states, including subsequent graviton decay into the dilepton or diphoton pairs.

The calculation is based on the KaTie package for an automated calculation of the partonic process in high-energy factorization, making use of TMD parton densities implemented in TMDlib.

Top and EW physics at the LHeC and the FCC-eh The European Physical Society Conference on High Energy Physics, EPS-HEP2017, Meeting locationVenice, Italy, 5 Jul 2017 - 12 Jul 2017 464 pp. (2018) [10.3204/PUBDB-2017-13942]   The Large Hadron-electron Collider LHeC and the Future Circular Collider in electron-hadron mode FCC-eh will provide electron-proton collisions with center-of-mass energies in the range 1.3-3.5 TeV and instantaneous luminosities larger than 1034 cm−2s−1. The talk presents an overview on novel and unique top physics through single and pair production in ep collisions, including prospects for measurements of top quantum numbers, anomalous and CKM couplings, as well as prospects to measure the parton momentum fraction carried by the top when the proton is probed at very high momenta.

These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of $\sqrt s =1.96$ TeV.

The razor variables $M_\mathrm{R}$ and $\mathrm{R}^2$, as well as the momentum and mass resolution of the diphoton system, are used to categorize events into different search regions.
