Search for a vector gauge boson in ϕ meson decays with the KLOE detector
Abstract The existence of a light dark force mediator has been tested with the KLOE detector at DAΦNE. This particle, called U, is searched for using the decay chain ϕ → η ...

The next-to-leading order vertex for a forward jet plus a rapidity gap at high energies
Abstract We present the results for the calculation of the forward jet vertex associated to a rapidity gap (coupling of a hard pomeron to the jet) in the Balitsky–Fadin–Kuraev–Lipatov (BFKL) formalism at next-to-leading order (NLO). We handle the...

Study of the Cabibbo-suppressed decay modes D0→π−π+ and D0→K−K+
Abstract Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement for the branching ratios of the Cabibbo-suppressed decay modes D 0→π − π ...

Closing up a light stop window in natural SUSY at LHC
Abstract Top squark (stop) plays a key role in the radiative stability of the Higgs boson mass in supersymmetry (SUSY). In this work, we use the LHC Run-1 data to determine the lower mass limit of the right-handed stop in a natural SUSY scenario,...

Time evolutions of scalar field perturbations in D-dimensional Reissner–Nordström Anti-de Sitter black holes
Abstract Reissner–Nordström Anti-de Sitter (RNAdS) black holes are unstable against the charged scalar field perturbations due to the well-known superradiance phenomenon. We present the time domain analysis of charged scalar field perturbations in...

Inclusive production of the η and ω mesons in Z decays, and the muonic branching ratio of the ω
Abstract The inclusive production of the η and ω(782) mesons is measured in the π + π − π 0 decay mode in hadronic Z decays and compared to...

Crystal acceleration effect for cold neutrons in the vicinity of the Bragg resonance
Abstract A new mechanism of neutron acceleration is studied experimentally in detail for cold neutrons passing through the accelerated perfect crystal with the energies close to the Bragg one. The effect arises due to the following reason. The...

Ab initio study of neutron drops with chiral Hamiltonians
Abstract We report ab initio calculations for neutron drops in a 10 MeV external harmonic-oscillator trap using chiral nucleon–nucleon plus three-nucleon interactions. We present total binding energies, internal energies, radii and odd–even energy...

First spatial separation of a heavy ion isomeric beam with a multiple-reflection time-of-flight mass spectrometer
Abstract 211Po ions in the ground and isomeric states were produced via 238U projectile fragmentation at 1000 MeV/u. The 211Po ions were spatially separated in flight from the primary beam and other reaction products by the...

Search for heavy neutral and charged leptons in e+e− annihilation at LEP
Abstract A search for exotic unstable neutral and charged heavy leptons as well as for stable charged heavy leptons is performed with the L3 detector at LEP. Sequential, vector and mirror natures of heavy leptons are considered. No evidence for...

Search for colour singlet and colour reconnection effects in hadronic Z decays at LEP
Abstract A search is performed in symmetric 3-jet hadronic Z-decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of particles are found to be sensitive indicators of such...

Multi-hadron final states in RPV supersymmetric models with extra matter
Abstract The gluino mass has been constrained by various search channels at the LHC experiments and the recent analyses are even sensitive to the cases where gluinos decay to quarks at the end of the decay chains through the baryonic RPV operator....
