e+e- --> e+e- pi0 pi0 at Daphne

, 2006
The production of the sigma(500) meson in gamma gamma --> pi0 pi0 is studied. In particular, the KLOE data collected during the DAPHNE run at sqrt(s)= 1 GeV are appropriate to this purpose because of the strong reduction of Kaon backgrounds.Comment: 13 ...

Quaero@H1: An Interface to High-pT HERA Event Data [PDF]

, 2006
Distributions from high-pT HERA event data analyzed in a general search for new physics at H1 have been incorporated into Quaero, an algorithm designed to automate tests of specific hypotheses with high energy collider data.

NLO photon parton parametrization using ee and ep data

, 2005
An NLO photon parton parametrization is presented based on the existing $F_2^\gamma$ measurements from $e^+e^-$ data and the low-$x$ proton structure function from $ep$ interactions.

Remarks Concerning the Study of Four-Jet Events from Hadronic Decays of the Z0 [PDF]

, 2006
The angular correlations of four-jet events from hadronic decays of the Z0 have been studied in the past mainly to extract from them the fundamental constants of quantum chromodynamics called colour factors.

A new gamma*-p / pbar-p factorization test in diffraction, valid below Q^2 about 6 GeV^2

, 2003
One of the key experimental issues in high energy hadron physics is the extent to which data from the diffractive interaction mechanism may be described by a factorized formula which is the product of a universal term describing the probability of ...

Isospin constraints from/on B->pipi

, 2004
The Standard Model constraints on alpha which can be derived from the B-> pipi decays are revisited in some depth. As experimental inputs, the three branching ratios, the two CP parameters Spipi and Cpipi and/or the value of alpha as determined by the ...

LHC Coverage of RPV MSSM with Light Stops

, 2013
We examine the sensitivity of recent LHC searches to signatures of supersymmetry with R-parity violation (RPV). Motivated by naturalness of the Higgs potential, which would favor light third-generation squarks, and the stringent LHC bounds on spectra in ...

CMS reconstruction improvement for the muon tracking by the RPC chambers

, 2012
The contribution of Resistive Plate Chamber (RPC) to muon reconstruction in CMS has been studied on a sample of muons collected in proton-proton collisions at sqrt(s) = 7 TeV at the LHC in 2011.

Log(1/x) Gluon Distribution and Structure Functions in the Loop-Loop Correlation Model

, 2003
We consider the interaction of the partonic fluctuation of a scalar ``photon'' with an external color field to calculate the leading and next-to-leading order gluon distribution of the proton following the work done by Dosch-Hebecker-Metz-Pirner.

Search for High-energy Neutrinos from Binary Neutron Star Merger GW170817 with ANTARES, IceCube, and the Pierre Auger Observatory [PDF]

, 2017
The Advanced LIGO and Advanced Virgo observatories recently discovered gravitational waves from a binary neutron star inspiral. A short gamma-ray burst (GRB) that followed the merger of this binary was also recorded by the FermiGamma-ray Burst Monitor ...
