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…

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…
