An improved limit for eeof X(3872)and eemeasurement ofψ(3686)
(2015)
Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e-→γISRX(3872)→γISRπ+π-J/ψ via the Initial State Radiation technique. The ...
Evidence for e+e−→γχc1,2at center-of-mass energies from4.009 to 4.360 GeV
(2015)
Using data samples collected at center-of-mass energies of s = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e- → γχcJ (J=0, 1, 2) and ...
Study ofeþe−→ωχcJat 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-→ωχcJ (J=0, 1, 2). The process e+e-→ωχc0 is observed ...
Search for new phenomena in dijet angular distributions in proton-proton collisions at root s=8 tev measured with the atlas detector
(2015)
A search for new phenomena in LHC proton-proton collisions at a center-of-mass energy of root s = 8 TeV was performed with the ATLAS detector using an integrated luminosity of 17.3 fb(-1). The angular distributions are ...
Search for scalar charm quark pair production in pp collisions at root s=8 tev with the atlas detector
(2015)
The results of a dedicated search for pair production of scalar partners of charm quarks are reported. The search is based on an integrated luminosity of 20.3 fb(-1) of pp collisions at root s = 8 TeV recorded with the ...
Observation of theψð13D2ÞState ineþe−→πþπ−γχc1at BESIII
(2015)
We report the observation of the X(3823) state in the process e+e-→π+π-X(3823)→π+π-γχc1with a statistical significance of 6.2σ, in data samples at center-of-mass energies s √s=4.230, 4.260, 4.360, 4.420, and 4.600 GeV ...
Observation of a neutral structure near the d(d)over-bar* mass threshold in e(+)e(-) -> (d(d)over-bar*)(0)pi(0) at root s=4.226 and 4.257 gev
(2015)
A neutral structure in the D (D) over bar* system around the D (D) over bar* mass threshold is observed with a statistical significance greater than 10 sigma in the processes e(+)e(-) -> D+D*(-)pi(0) + c.c. and e(+)e(-) ...
Measurement of the Absolute Branching Fraction forΛþc→Λeþν
(2015)
We report the first measurement of the absolute branching fraction for Λc+→Λe+νe. This measurement is based on 567 pb-1 of e+e- annihilation data produced at s=4.599 GeV, which is just above the Λc+Λ¯c- threshold. The data ...
