$\sqrt{s}=$ 13 ... | hep-ex |
Measurement of the cross-section ratio
$σ(χ_{c2})/σ(χ_{c1})$ for prompt $χ_c$ production at
$\sqrt{s}=7$ TeV: The prompt production of the charmonium $\chi_{c1}$ and $\chi_{c2}$ mesons
has been studied in proton-proton collisions at the Large Hadron Collider at a
centre-of-mass energy of $\sqrt{s}=7$ TeV. The $\chi... | hep-ex |
A Measurement of the K0 Charge Radius and a CP Violating Asymmetry
Together with a Search for CP Violating E1 Direct Photon Emission in the Rare
Decay KL->pi+pi-e+e-: Using the complete KTeV data set of 5241 candidate KL->pi+pi-e+e- decays
(including an estimated background of 204+-14 events), we have measured the

photon+jet event rate estimation for the gluon distribution
determination at the Tevatron Run II: Since a lot of theoretical predictions on the production of new particles
(Higgs, SUSY) at the Tevatron are based on model estimations of the proton
gluon density behavior at low $x$ and high values of a transfered momen... | hep-ex |
Studies of $X(3872)$ and $ψ(2S)$ production in $p\bar{p}$ collisions
at 1.96 TeV: We present various properties of the production of the $X(3872)$ and
$\psi(2S)$ states based on 10.4 fb$^{-1}$ collected by D0 experiment in
Tevatron $p \bar p$ collisions at $\sqrt{s}$ = 1.96 TeV. For both states, we
measure the nonpro... | hep-ex |
Top-quark mass at hadron colliders: Top quarks can be produced abundantly at hadron colliders like the Tevatron
at Fermilab and the Large Hadron Collider at CERN, and a variety of
measurements of top-quark properties have been gathered in the recent years
from four experiments: CDF and D0 at the Tevatron and ATLAS and ... | hep-ex |
Measurements of jet-related observables at the LHC: During the first years of the LHC operation a large amount of jet data was
recorded by the ATLAS and CMS experiments. In this review several measurements
of jet-related observables are presented, such as multi-jet rates and cross
sections, ratios of jet cross sections... | hep-ex |
Nucleon Electromagnetic Form Factors in the Timelike Region: The electromagnetic form factors of the proton and the neutron in the
timelike region are reviewed. In view of the forthcoming experimental projects
devoted to investigate these observables, we present the current status of the
field and we emphasize the rele... | hep-ex |
Recent structure function results from neutrino scattering at Fermilab: We report on the extraction of the structure functions F_2 and Delta xF_3 =
xF_3(nu)-xF_3(nubar) from CCFR nu_mu-Fe and nubar_mu-Fe different ial cross
sections. The extraction is performed in a physics model independent (PMI) way.
This first measu... | hep-ex |
Recent Results on Light-Meson Spectroscopy from COMPASS: The main goal of the spectroscopy program at COMPASS is to explore the
light-meson spectrum below about $2\,\text{GeV}/c^2$ in diffractive production.
Our flagship channel is the decay into three charged pions: $p + \pi^-\to
\pi^-\pi^-\pi^+ + p_\text{recoil}$, fo... | hep-ex |
