Combined measurement of the higgs boson mass in pp collisions at root s=7 and 8 tev with the atlas and cms experiments
(2015)
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H -> gamma gamma and H -> ZZ -> 4l decay channels. The results are obtained from ...
Observation of an excited b-c(+/-) meson state with the atlas detector
(2015)
A search for excited states of the B-c(+/-) meson is performed using 4.9 fb(-1) of 7 TeV and 19.2 fb(-1) of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through its hadronic ...
Observation of z(c)(3900)(0) in e(+)e(-) -> pi(0)pi(0) j/psi
(2015)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z(c)(3900)(0) with a significance of 10.4 sigma. The mass and width are measured to be 3894.8 +/- ...
Search for higgs boson pair production in the gamma gamma b(b)over-bar final state using pp collision data at root s=8 tev from the atlas detector
(2015)
Searches are performed for resonant and nonresonant Higgs boson pair production in the gamma gamma b (b) over bar final state using 20 fb(-1) of proton-proton collisions at a center-of-mass energy of 8 TeV recorded with ...
Measurements of the nuclear modification factor for jets in pb plus pb collisions at root snn=2.76 tev with the atlas detector
(2015)
Measurements of inclusive jet production are performed in pp and Pb + Pb collisions at root SNN = 2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 and 0.14 nb(-1), respectively. ...
Study of e(+)e(-) -> omega chi(cj) at center of mass energies from 4.21 to 4.42 gev
(2015)
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e(+)e(-) -> omega chi(cJ) (J = 0, 1, 2). The process ...
Search for dark matter in events with missing transverse momentum and a higgs boson decaying to two photons in pp collisions at root s=8 tev with the atlas detector
(2015)
Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and ...
Search for a heavy neutral particle decaying to e mu, e tau, or mu tau in pp collisions at root s=8 tev with the atlas detector
(2015)
This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e(+/-) mu(-/+), e(+/-) tau(-/+), or mu(+/-) tau(-/+) using 20.3 fb(-1) of pp collision data at root ...
Observation and spin-parity determination of the x(1835) in j/psi -> gamma(ksks0)-k-0 eta
