Full homomorphisms to graph classes
Pavol Hell, César Hernández-Cruz
Given a family of graphs , we define a graph to be fully -colourable if admits a full homomorphism to some in . We approach the p…
Search for the charged lepton flavour violating decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +765
Based on events collected in collisions at GeV with the BESIII detector, we present a search for the charged lepton flavou…
Precision measurements of semleptonic decays and ()
BESIII Collaboration, M. Ablikim, M. N. Achasov +773
The branching fractions of , , , and are measured to be $(2.950\pm0.017_{\rm stat.}\pm 0.017_{\…
Study of the process from = 4.42 to 4.95 GeV at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +782
Based on of collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…
Measurement of Born cross sections for at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
We report a measurement of the Born cross section and the effective form factor for the reaction at 47 center-of-mass energies between 3.510 and 4.946 GeV. The…
Observation of and Measurement of Electromagnetic Form Factors of Proton at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
We search for possible charmonium(-like) states decaying into the final state by studying the Born cross sections of the reaction, and we determine…
