Possible small- x effects in the Kaluza-Klein graviton and radion production at high energies
[DESY-17-038; arXiv:1612.03811] ddc:530
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.

Calculations with off-shell matrix elements, TMD parton densities and TMD parton showers
[IFJPAN-IV-2017-28; DESY-17-222; arXiv:1712.05932] ddc:530
A new calculation using off-shell matrix elements with TMD parton densities supplemented with a newly developed initial state TMD parton shower is described. 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. [...]

[PUBDB-2018-01272] Contribution to a conference proceedings

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 20172017-07-052017-07-12 464 pp. (2018) [10.3204/PUBDB-2017-13942]  GO
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.

Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron
[FERMILAB-PUB-17-379-E; arXiv:1709.04894] ddc:550
The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of $\sqrt s =1.96$ TeV. [...]

[CMS-HIN-16-021; CERN-EP-2017-261; arXiv:1710.09355] ddc:530
The pseudorapidity distributions of charged hadrons in proton-lead collisions at nucleon-nucleon center-of-mass energies $ \sqrt{s_{\mathrm{NN}}}=5.02 $ and 8.16 TeV are presented. The measurements are based on data samples collected by the CMS experiment at the LHC. [...]

Search for supersymmetry with Higgs boson to diphoton decays using the razor variables at $\sqrt{s}=$ 13 TeV
[CMS-SUS-16-045; CERN-EP-2017-158; arXiv:1709.00384] ddc:530
An inclusive search for anomalous Higgs boson production in the diphoton decay channel and in association with at least one jet is presented, using LHC proton-proton collision data collected by the CMS experiment at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 35.9 fb$^{-1}$. 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. [...]

Observation of medium induced modifications of jet fragmentation in PbPb collisions using isolated-photon-tagged jets
[CMS-HIN-16-014; CERN-EP-2017-337; arXiv:1801.04895]
Measurements of fragmentation functions for jets associated with an isolated photon are presented for the first time in pp and PbPb collisions. The analysis uses data collected with the CMS detector at the CERN LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. [...]

Search for dark matter in events with energetic, hadronically decaying top quarks and missing transverse momentum at $\sqrt{s}=$ 13 TeV
[CMS-EXO-16-051; CERN-EP-2017-299; arXiv:1801.08427; CMS-EXO-16-051; CERN-EP-2017-299]
A search for dark matter is conducted in events with large missing transverse momentum and a hadronically decaying, Lorentz-boosted top quark. This study is performed using proton-proton collisions at a center-of-mass energy of 13 TeV, in data recorded by the CMS detector in 2016 at the LHC, corresponding to an integrated luminosity of 36 fb$^{-1}$.
