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…
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_{\…
Amplitude analysis and branching fraction measurement of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
An amplitude analysis of the decay is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^…
Search for an isoscalar partner of the in
BESIII Collaboration, M. Ablikim, M. N. Achasov +684
Using a data sample corresponding to an integrated luminosity of 20.3 fb collected at center-of-mass energies from 4.18 to 4.95 GeV with the BESIII detector, we observe the…
Observation and branching fraction measurements of and
BESIII Collaboration, M. Ablikim, M. N. Achasov +765
Using events and events collected by the BESIII detector operating at the BEPCII collider, we report the…
First Observation of and Determination of the Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using 20.3~fb of annihilation data collected at a center-of-mass energy of 3.773~GeV with the BESIII detector, we report the first observation of the semileptonic d…
