Possible small x effects in the KaluzaKlein graviton and radion production at high energies
[DESY17038; arXiv:1612.03811]
ddc:530
We study the single graviton production at the CERN LHC using the kTfactorization approach of QCD. We consider the ArkaniHamedDimopoulosDvali scenario and RandallSundrum model with one warped extra dimension and derive the production amplitudes for spin2 (KaluzaKlein excitation of the graviton) and spin0 (radion) states, including subsequent graviton decay into the dilepton or diphoton pairs.

Calculations with offshell matrix elements, TMD parton densities and TMD parton showers
[IFJPANIV201728; DESY17222; arXiv:1712.05932]
ddc:530
A new calculation using offshell 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 highenergy factorization, making use of TMD parton densities implemented in TMDlib. [...]

Measurement of $Z$boson production cross sections at √s = 13 TeV and $t\bar{t}$ to $Z$boson crosssection ratios with the ATLAS detector at the LHC
[DESYTHESIS2018004]
Hamburg : Verlag Deutsches ElektronenSynchrotron, DESYTHESIS, 196 pp. (2018) [10.3204/PUBDB201801266] = Dissertation, Universität Hamburg, 2018
The measurement of $Z$boson production cross sections in $pp$ collisions at centreofmass energy of √s = 13 TeV is presented. Results are based on data corresponding to an integrated luminosity of 3.16 fb$^{1}$ recorded with the ATLAS detector in 2015 at the LHC operating with the 25 ns bunch spacing configuration. [...]

Measurements of the absolute branching fractions of $\mathrm{B^ + → X _{c \bar{c}} K ^+}$ and $\mathrm{B^ + → \bar{D} ^{( * ) 0} π^ +}$ at Belle
[arXiv:1709.06108]
ddc:530
We present the measurement of the absolute branching fractions of $B^{+} \to X_{c\bar{c}} K^{+}$ and $B^{+} \to \bar{D}^{(\ast) 0} \pi^{+} $ decays, using a data sample of $772\times10^{6}$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetricenergy $e^{+}e^{}$ collider. Here, $X_{c\bar{c}}$ denotes $\eta_{c}$, $J/\psi$, $\chi_{c0}$, $\chi_{c1}$, $\eta_{c}(2S)$, $\psi(2S)$, $\psi(3770)$, $X(3872)$, and $X(3915)$. [...]

Njettiness subtractions for g g → H at subleading power
[DESY17128]
ddc:530
Njettiness subtractions provide a general approach for performing fullydifferential nexttonexttoleading order (NNLO) calculations. Since they are based on the physical resolution variable Njettiness, $\mathcal{T}$N, subleading power corrections in $\tau=\mathcal{T}$N/Q, with Q a hard interaction scale, can also be systematically computed [...]

With the identification of a diffuse flux of astrophysical ('cosmic') neutrinos in the TeVPeV energy range, IceCube has opened a new window to the Universe. However, the corresponding cosmic landscape is still uncharted: so far, the observed flux does not show any clear association with known source classes. [...]

We describe a procedure for extracting momentum derivatives of nucleon matrix elements on the lattice directly at $Q^2=0$. This is based on the Rome method for computing momentum derivatives of quark propagators. [...]

Electron and photon reconstruction and performance in ATLAS using a dynamical, topological cell clusteringbased approach
[ATLPHYSPUB2017022]
This note presents the reconstruction of electrons and photons in ATLAS using a dynamic,topological cell clusteringbased approach. This new technique allows for improved measurements of electron and photon energies, particularly in situations where an electron radiatesa bremsstrahlung photon, or a photon converts to an electronpositron pair.

An in situ investigation of the deformation mechanisms in a βquenched Ti5Al5V5Mo3Cr alloy
[I20150533 EC]
ddc:600
The sequence of activation of deformation mechanisms in a nearβ Ti5Al5Mo5V3Cr alloy quenched from the βfield is investigated as a function of strain during uniaxial compression at 0.001 s$^{−1}$ up to $ε$ = 0.041. Bulk in situ high energy synchrotron Xray diffraction is applied to follow continuously the evolution of the microstructure of the alloy during deformation and is complemented with metallographic analysis.
