and interprets t... | hep-ex |
Charmed Hadrons from Fragmentation and B Decays: The fragmentation functions of $D^0$, $D^{\pm}$, $D_s^{\pm}$, $D^{*o}$,
$D^{*\pm}$ and $\Lambda_c^{\pm}$ at $\sqrt{s}$$\simeq$10.6 GeV are measured
with a data set of 102.7 fb$^{-1}$. Fragmentation model parametrizations
(Peterson, Kartvelishvili, Collins-Spiller, Lund, ... | hep-ex |
Elliptic flow of charm and strange hadrons in high-multiplicity pPb
collisions at $\sqrt{s_{_\mathrm{NN}}} =$ 8.16 TeV: The elliptic azimuthal anisotropy coefficient ($v_2$) is measured for charm
(D$^0$) and strange (K$_\mathrm{S}^0$, $\Lambda$, $\Xi^-$, and $\Omega^-$)
hadrons, using a data sample of pPb collisions ... | hep-ex |
Search for Extra Dimensions in the Diphoton Channel: We present a search for extra dimensions in the diphoton channel using the
CMS detector at the Large Hadron Collider. The search is focused on the
forthcoming 2009--2010 run at 10 TeV center$-$of$-$mass energy and $\sim 100$
pb$^{-1}$ of data. We discuss event select... | hep-ex |
Study of hard double-parton scattering in four-jet events in $pp$
collisions at $\sqrt{s} = 7$ TeV with the ATLAS experiment: Inclusive four-jet events produced in proton-proton collisions at a
centre-of-mass energy of $\sqrt{s} = 7$ TeV are analysed for the presence of
hard double-parton scattering using data corres... | hep-ex |
Observation of a diffractive contribution to dijet production in
proton-proton collisions at $\sqrt{s} = 7$ TeV: The differential cross section measurement for dijet production at
proton-proton collisions at $\sqrt{s}=7$ TeV is presented as a function of an
approximation for the fractional momentum loss of the scatte... | hep-ex |
The Physics of Deep-Inelastic Scattering at HERA: In this paper an introduction to the physics of deep-inelastic scattering is
given together with an account of some of the most recent results on the proton
structure obtained in electron-- and positron--proton collisions at the HERA
collider. | hep-ex |
Measurements of Neutrino Cross Sections Near 1 GeV: We summarise recent neutrino and antineutrino measurements near 1 GeV by the
K2K, MiniBooNE and SciBooNE collaborations. We focus on experimental methods
and note discrepancies between the most commonly used models for
neutrino-nucleus interactions and recent high sta... | hep-ex |
Some Properties of the Very High Q^2 Events of HERA: The kinematic reconstruction of neutral current high Q^2 events at HERA is
discussed in detail using as an example the recently published events of the H1
and ZEUS collaborations at Q^2 > 15000 GeV^2 and M > 180 GeV, which are more
numerous than expected from Standar... | hep-ex |
Measurement of the neutrino mixing angle $θ_{23}$ in NOvA: This Letter reports new results on muon neutrino disappearance from NOvA,
using a 14 kton detector equivalent exposure of $6.05\times10^{20}$
protons-on-target from the NuMI beam at the Fermi National Accelerator
Laboratory. The measurement probes the muon-tau ... | hep-ex |
