EPJ C - Neutrons escaping to a parallel world?

An anomaly in the behaviour of ordinary particles may point to the existence of mirror particles that could be candidates for dark matter responsible for the missing mass of the universe. In a paper recently published in EPJC, researchers hypothesised the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter had been suggested in various scientific contexts some time ago, including the search for suitable dark matter candidates.

EPJ C - "Spooky action at distance" in particle physics?!

Physicists have developed the first conclusive test to better understand high-energy particles correlations.

Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as "Bell’s nonlocality". This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called "CP violation" principle, which is used to explain the dominance of matter over antimatter. These findings by Beatrix Hiesmayr, a theoretical physicist at the University of Vienna, and her colleagues, a team of quantum information theory specialists, particle physicists and nuclear physicists, have been published in EPJC.

EPJ C - New Theory Editors-in-Chief and Fermi Prize for Dieter Haidt

The publishers of The European Physical Journal C – Particles and Fields are pleased to announce the appointment of Professors Gino Isidori (Frascati) and Sergei Odintsov (Barcelona) as new theory Editors-in-Chief. This follows the splitting of the theory section into Theory I: Phenomenology of the Standard Model and Beyond, now led by Gino Isidori, and Theory II: Gravitation, Astroparticle Physics and Cosmology, General Aspects of Quantum Field Theories and Alternatives, now led by Sergei Odintsov.

EPJ C - No sign of supersymmetry

Most stringent limits ever set by ATLAS

"Supersymmetry - to be or not to be?" remains a still unanswered question - it is a traditionally difficult business to demonstrate a zero result in experimental physics - yet the ATLAS collaboration has just set new and very stringent limitations on the "viability space" of a class of new physics models incorporating gauge-mediated supersymmetry breaking.

EPJ C article selected Fast Breaking Paper by ScienceWatch

The physics paper with the highest percentage increase in citations so far in 2010, as determined by ScienceWatch.com, is `Parton distributions for the LHC' by A Martin et al. Eur.Phys.J.C63:189-285, 2009 This article has meanwhile been cited over 200 times, according to the reference database for high-energy physics, SPIRES. The paper was already selected as highlighted article by the editorial board of EPJ C, featuring on the cover of the September 2009 issue of this journal.

First proton–proton collisions at the LHC as observed with the ALICE detector

Figure shows the first pp collision candidate by the event display in the ALICE counting room (3D view).

On 23rd November 2009, during the early commissioning of the CERN Large Hadron Collider (LHC), two counter-rotating proton bunches were circulated for the first time concurrently in the machine, at the LHC injection energy of 450 GeV per beam, allowing all LHC experiments to report first collision candidates.

284 such candidates were recorded by the ALICE experiment, allowing the events to be immediately reconstructed and analyzed. The results obtained by measuring the spatial distribution (specifically, the pseudorapidity density) of charged primary particles in the central region, were found to be consistent with previous measurements in proton-antiproton interactions at the same centre-of-mass energy at the CERN SppS collider (UA5 Collaboration, G.J. Alner et al., Z Phys. C 33 (1986), DOI 10.1007/BF01410446).

J Schukraft, the ALICE spokesman, said: This important benchmark test illustrates also the excellent functioning and rapid progress of the LHC accelerator, and of both the hardware and software of the ALICE experiment, in this early start-up phase.

EPJ C further extends OA publishing scheme

Following the completion of the first period (2007-2008) of its OA publishing scheme, and in anticipation of successful negotiations with interested Open Access funding agencies in the future, the "open access" publishing fees for all experimental papers submitted to and accepted for publication by The European Physical Journal C - Particles and Fields will continue to be waived. The paper categories concerned are both regular articles and scientific notes, on experimental physics. Independently, all Letters continue to be published "open access" by default, without any fees being incurred by the authors.

EPJ C appoints new theory Editor-in-Chief

Prof. Georg Weiglein (University of Durham, UK) has been appointed the new Editor-in-Chief for theoretical particle and high-energy physics of The European Physical Journal (EPJ) C. He leads the journal into the hot phase of LHC physics and works together with Prof. Siegfried Bethke (MPI Munich, Germany), Editor-in-Chief for experimental physics. Georg Weiglein succeeds Jochen Bartels (University of Hamburg, Germany), who had been the journal's theory Editor-in-Chief since 1999. Jochen Bartels and Dieter Haidt (DESY, Hamburg) together successfully shaped the profile of EPJC, after the merger of the famous journals Zeitschrift für Physik C and Il Nuovo Cimento A, back in 1998.

EPJ C extends OA publishing scheme

In anticipation of successful negotiations with interested Open Access funding agencies, as of today and until such negotiations have taken place before or by the end of 2008, all experimental papers submitted to and accepted by The European Physical Journal C - Particles and Fields will be published with full, online open access without any fees being incurred by the authors.
