Using J/psi radiative decays from 9.0 billion J/psi events collected by the BESIII detector, we search for di-muon decays of a CP-odd light Higgs boson (A(0)), predicted by many new physics models beyond the Standard Model, ...

The process e(+)e(-) -> phi eta is studied at 22 center-of-mass energy points (root s) between 2.00 and 3.08 GeV using 715 pb(-1) of data collected with the BESIII detector. The measured Born cross section of e(+)e(-) -> ...

Based on electron-positron collision data collected with the BESIII detector operating at the Beijing Electron-Positron Collider II storage rings, the value of Rσ(e+e-→hadrons)/σ(e+e-→μ+μ-) is measured at 14 center-of-mass ...

Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb-1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon-number and ...

The cross section of the process e(+)e(-) -> omega pi(0)pi(0) is measured at nineteen center-of-mass energies from 2.0 to 3.08 GeV using data collected with the BESIII detector at the BEPCII storage ring. A resonant structure ...

A search for invisible decays of the Λ baryon is carried out in the process J/ψ→ΛΛ¯ based on (1.0087±0.0044)×1010 J/ψ events collected with the BESIII detector located at the BEPCII storage ring. No signals are found for ...

Using e+e-annihilation data corresponding to a total integrated luminosity of 6.32 fb-1 collected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the ...

Using 5.9 pb(-1) of e(+)e(-) annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e(+)e(-) -> (KSX)-X-0 ...

Using 2.93 fb-1 of e+e- collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present a measurement of the branching fraction of the doubly Cabibbo-suppressed (DCS) decay D0→K+π-π0 ...

Though immensely successful, the standard model of particle physics does not offer any explanation as to why our Universe contains so much more matter than antimatter. A key to a dynamically generated matter-antimatter ...
