Measurement of the charge asymmetry in top-quark pair production in proton-proton collisions at sqrt(s) = 7 TeV

CMS Collaboration

The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experi…

Resonances in 19Ne with relevance to the astrophysically important 18F(p,α)15O reaction

D. J. Mountford, A. St J. Murphy, N. L. Achouri +11

The most intense gamma-ray line observable from novae is likely to be from positron annihilation associated with the decay of 18F. The uncertainty in the destruction rate of this n…

Bilocal versus non-bilocal correlations in entanglement swapping experiments

Cyril Branciard, Denis Rosset, Nicolas Gisin +1

Entanglement swapping is a process by which two initially independent quantum systems can become entangled and generate nonlocal correlations. To characterize such correlations, we…

The tensor part of the Skyrme energy density functional. III. Time-odd terms at high spin

V. Hellemans, P. -H. Heenen, M. Bender

This article extends previous studies on the effect of tensor terms in the Skyrme energy density functional by breaking of time-reversal invariance. We have systematically probed t…

Gravitational Actions in Two Dimensions and the Mabuchi Functional

Frank Ferrari, Semyon Klevtsov, Steve Zelditch

The Mabuchi energy is an interesting geometric functional on the space of Kähler metrics that plays a crucial rôle in the study of the geometry of Kähler manifolds. We show that th…

Masses of neutron stars and nuclei

N. Chamel, A. F. Fantina, J. M. Pearson +1

We calculate the maximum mass of neutron stars for three different equations of state (EOS) based on generalized Skyrme functionals that are simultaneously fitted to essentially al…

Phase transitions of quasistationary states in the Hamiltonian Mean Field model

Pierre de Buyl, Duccio Fanelli, Stefano Ruffo

The out-of-equilibrium dynamics of the Hamiltonian Mean Field (HMF) model is studied in presence of an externally imposed magnetic field h. Lynden-Bell's theory of violent relaxati…

Collider signatures of goldstini in gauge mediation

Riccardo Argurio, Karen De Causmaecker, Gabriele Ferretti +3

We investigate the collider signatures of the multiple goldstini scenario in the framework of gauge mediation. This class of models is characterized by a visible sector (e.g. the M…

Simple matrix models for random Bergman metrics

Frank Ferrari, Semyon Klevtsov, Steve Zelditch

Recently, the authors have proposed a new approach to the theory of random metrics, making an explicit link between probability measures on the space of metrics on a Kahler manifol…

The definition of multipartite nonlocality

Jean-Daniel Bancal, Jonathan Barrett, Nicolas Gisin +1

In a multipartite setting, it is possible to distinguish quantum states that are genuinely -way entangled from those that are separable with respect to some bipartition. Similar…

Search for signatures of extra dimensions in the diphoton mass spectrum at the Large Hadron Collider

CMS Collaboration

A search for signatures of extra dimensions in the diphoton invariant-mass spectrum has been performed with the CMS detector at the LHC. No excess of events above the standard mode…

The Four Basic Ways of Creating Dark Matter Through a Portal

Xiaoyong Chu, Thomas Hambye, Michel H. G. Tytgat

We consider the possibility that along the thermal history of the Universe, dark matter (DM) would have been created from Standard Model particles, either through a kinetic mixing…
