Measurement of the Inclusive Upsilon production cross section in pp collisions at sqrt(s)=7 TeV
CMS Collaboration
The Upsilon production cross section in proton-proton collisions at sqrt(s) = 7 TeV is measured using a data sample collected with the CMS detector at the LHC, corresponding to an…
Search for Pair Production of Second-Generation Scalar Leptoquarks in pp Collisions at sqrt(s) = 7 TeV
The CMS Collaboration
A search for pair production of second-generation scalar leptoquarks in the final state with two muons and two jets is performed using proton-proton collision data at sqrt(s) = 7 T…
Search for Pair Production of First-Generation Scalar Leptoquarks in pp Collisions at sqrt(s) = 7 TeV
The CMS Collaboration
A search for pair production of first-generation scalar leptoquarks is performed in the final state containing two electrons and two jets using proton-proton collision data at sqrt…
Phase Estimation from Atom Position Measurements
Jan Chwedenczuk, Francesco Piazza, Augusto Smerzi
We study the measurement of the position of atoms as a means to estimate the relative phase between two Bose-Einstein condensates. First, we consider atoms released from a doub…
Fluctuations in the Ensemble of Reaction Pathways
G. Mazzola, S. a Beccara, P. Faccioli +1
The dominant reaction pathway (DRP) is a rigorous framework to microscopically compute the most probable trajectories, in non-equilibrium transitions. In the low-temperature regime…
Metastability in spin polarised Fermi gases and quasiparticle decays
Kayvan Sadeghzadeh, Georg Bruun, Carlos Lobo +2
We investigate the metastability associated with the first order transition from normal to superfluid phases in the phase diagram of two-component polarised Fermi gases.We begin by…
Static Spherically Symmetric Solutions in F(R) Gravity
Lorenzo Sebastiani, Sergio Zerbini
A Lagrangian derivation of the Equation of Motion (EOM) for static spherically symmetric metrics in F(R) modified gravity is presented. For a large class of metrics, our approach p…
Fermi-Liquid Behavior of the Normal Phase of a Strongly Interacting Gas of Cold Atoms
Sylvain Nascimbène, Nir Navon, Sebastiano Pilati +4
We measure the magnetic susceptibility of a Fermi gas with tunable interactions in the low-temperature limit and compare it to quantum Monte Carlo calculations. Experiment and theo…
Quantum Diffusive Dynamics of Macromolecular Transitions
S. a Beccara, G. Garberoglio, P. Faccioli
We study the role of quantum fluctuations of atomic nuclei in the real-time dynamics of non-equilibrium macro-molecular transitions. To this goal we introduce an extension of the D…
Non-singular exponential gravity: a simple theory for early- and late-time accelerated expansion
E. Elizalde, S. Nojiri, S. D. Odintsov +2
A theory of exponential modified gravity which explains both early-time inflation and late-time acceleration, in a unified way, is proposed. The theory successfully passes the loca…
Measurement of the Isolated Prompt Photon Production Cross Section in pp Collisions at sqrt(s) = 7 TeV
CMS Collaboration
The differential cross section for the inclusive production of isolated prompt photons has been measured as a function of the photon transverse energy E_T-gamma in pp collisions at…
Search for Stopped Gluinos in pp collisions at sqrt s = 7 TeV
CMS Collaboration
The results of the first search for long-lived gluinos produced in 7 TeV pp collisions at the CERN Large Hadron Collider are presented. The search looks for evidence of long-lived…
On the problem of van der Waals forces in dielectric media
Lev P. Pitaevskii
A short review of the problems which arise in the generalization of the Lifshitz theory of van der Waals force in the case of forces inside dielectric media is presented, together…
Frame dependence of 3He transverse (e,e') response functions at intermediate momentum transfers
Victor D. Efros, Winfried Leidemann, Giuseppina Orlandini +1
The transverse electron scattering response function of 3He was recently studied by us in the quasi-elastic peak region for momentum transfers q between 500 and 700 MeV/c. Those re…
Search for Dijet Resonances in 7 TeV pp Collisions at CMS
CMS Collaboration
A search for narrow resonances in the dijet mass spectrum is performed using data corresponding to an integrated luminosity of 2.9 inverse pb collected by the CMS experiment at the…
Density-dependent nucleon-nucleon interaction from three-nucleon forces
