High precision wavelength measurements of QED-sensitive forbidden transitions in highly charged argon ions
(Physical Review Letters, 2003)
We present the results of an experimental study of magnetic dipole (M1) transitions in highly charged argon ions (Ar X, Ar XI, Ar XIV, Ar XV) in the visible spectral range using an electron beam ion trap. Their wavelengths ...
New Isotopes and Proton Emitters-Crossing the Drip Line in the Vicinity of Sn-100
(American Physical Society, 2016)
Several new isotopes, In-96, Cd-94, Ag-92, and Pd-90, have been identified at the RIKEN Nishina Center. The study of proton drip-line nuclei in the vicinity of Sn-100 led to the discovery of new proton emitters Ag-93 and ...
D+(s0)(2317)-D-0(2308) mass difference as evidence for tetraquarks
(Physical Review Letters, 2005)
We argue that the anomalously small mass difference between the D-s0(+)(2317) and the recently observed D-0(2308) (Belle) state is the first smoking gun experimental evidence of their tetraquark [cq((qq) over bar)] structure. ...
Wedge-shaped potential and Airy-function electron localization in oxide superlattices
(Physical Review Letters, 2005)
Oxide superlattices and microstructures hold the promise for creating a new class of devices with unprecedented functionalities. Density-functional studies of the recently fabricated, lattice-matched perovskite titanates ...
Power controlled soliton stability and steering in lattices with saturable nonlinearity
(Physical Review Letters, 2004)
Dynamical properties of discrete solitons in nonlinear Schrodinger lattices with saturable nonlinearity are studied in the framework of the one-dimensional discrete Vinetskii-Kukhtarev model. Two stationary strongly localized ...
Search for Dark Matter and Large Extra Dimensions in pp Collisions Yielding a Photon and Missing Transverse Energy
(Physical Review Letters, 2012)
Results are presented from a search for new physics in the final state containing a photon (gamma) and missing transverse energy (is not an element of(T)). The data correspond to an integrated luminosity of 5.0 fb(-1) ...
Azimuthal Anisotropy of Charged Particles at High Transverse Momenta in Pb-Pb Collisions at root S-NN=2.76 TeV
(Physical Review Letters, 2012)
The azimuthal anisotropy of charged particles in Pb-Pb collisions at root S-NN = 2.76 TeV is measured with the CMS detector at the LHC over an extended transverse momentum (p(T)) range up to approximately 60 GeV/c. The ...
Production of Muons from Heavy Flavor Decays at Forward Rapidity in pp and Pb-Pb Collisions at root s(NN)=2.76 TeV
(Physical Review Letters, 2012)
The ALICE Collaboration has measured the inclusive production of muons from heavy-flavor decays at forward rapidity, 2.5 LT y LT 4, in pp and Pb-Pb collisions at root s(NN) = 2.76 TeV. The p(t)-differential inclusive cross ...
Search for Direct Top Squark Pair Production in Final States with One Isolated Lepton, Jets, and Missing Transverse Momentum in root s=7 TeV pp Collisions Using 4.7 fb(-1) of ATLAS Data
(Physical Review Letters, 2012)
A search is presented for direct top squark pair production in final states with one isolated electron or muon, jets, and missing transverse momentum in proton-proton collisions at root s = 7 TeV. The measurement is based ...
Search for a W or Techni-rho Decaying into WZ in pp Collisions at root s=7 TeV
(Physical Review Letters, 2012)
A search is performed in pp collisions at root s 7 TeV for exotic particles decaying via WZ to final states with electrons and muons. The data sample corresponds to an integrated luminosity of approximately 5 fb(-1). No ...
