Measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X: (BESIII Collaboration)
(Springer, 2020)
We report the first measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X. The analysis is performed using an e+e- collision data sample corresponding to an integrated luminosity of 567 ...
Study of the process e(+) e(-) -> pi(0)pi(0)J/psi and neutral charmoniumlike state Z(c)(3900)(0)
(Amer Physical Soc., 2020)
Cross sections of the process e(+)e(-) -> pi(0)pi(0)J/psi at center-of-mass energies between 3.808 and 4.600 GeV are measured with high precision by using 12.4 fb(-1) of data samples collected with the BESIII detector ...
Investigation of Breaking Points in the Airline Industry with Airline Optimization Studies Through Text Mining before the COVID-19 Pandemic
(Sage Publications Inc., 2021)
In this study, current literature in the field of airline optimization has been examined by the text mining method to understand trends and commercial threats in the airline industry. Prominent types of work and popular ...
Search for the Lepton Number Violating Decay Sigma(-) -> pe(-) e(-) and the Rare Inclusive Decay Sigma(-) -> Sigma(+) X
(Amer Physical Soc., 2021)
Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi events taken with the BESIII detector at the center-of-mass energy of 3.097 GeV, we search for the first time for the lepton number violating decay Sigma(-) -> pe(-) ...
An Experimental Study on Sustainability of Historical Wooden Buildings Exposed to Open Sea Streams
(Slovak Forest Products Research INST, 2020)
This research deals with the impact of the microclimate on historical wooden buildings exposed to open sea streams. The Florya Ataturk Marine Mansion in Istanbul, erected on the sea, totally defenceless to weather and sea ...
Observation of a Resonant Structure in e(+)e(-)-> Omega Eta and Another in e(+)e(-)-> Omega pi(0) at center-of-mass Energies Between 2.00 and 3.08 GeV
(Elsevier, 2021)
Born cross sections for the processes e(+)e(-) -> omega eta and e(+)e(-) -> omega pi(0) have been determined for centerof-mass energies between 2.00 and 3.08GeVwith the BESIII detector at the BEPCII collider. The results ...
Evaluation of enterprise investment attractiveness under circumstances of economic development
(SCIENDO, 2020)
This article introduces a step-by-step methodology for evaluating an enterprise's investment attractiveness in the context of economic development, using appropriate valuation parameters at macro, meso and micro levels. A ...
Observation of the decays chi(cJ) -> phi phi eta
(Amer Physical Soc., 2020)
Using a data sample of (448.1 +/- 2.9) x 10( )(6)psi(3686) decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays chi(cJ) -> phi phi eta (J = 0, 1, 2), where the ...
