Charmonium at BESIII [PDF]

open access: yesEPJ Web of Conferences, 2019
With large J/ψ and ψ(2S ) data samples, the BESIII Collaboration has performed many studies toward conventional charmonium states below energy 3.686 GeV, which provide information on the internal structure and the interactions of the mesons.

Exotics at BESIII [PDF]

open access: yesEPJ Web of Conferences, 2016
Using the 1.31 × 1010 J/ψ events and the data above open charm collected at BESIII detector, we studied and observed a lot of exotics, including X(3872), X(3823), Y(2175), Y(4140), Zc(3900), Zc(4020), and so on.

Light meson decays at BESIII [PDF]

open access: yesEPJ Web of Conferences, 2019
The BESIII experiment has accumulated the world’s largest data samples of 1.3 billion J/ψ events and 0.45 billion ψ(3686) events, which provide a unique opportunity to investigate light meson decays.

XYZ states at BESIII [PDF]

open access: yesEPJ Web of Conferences, 2019
In this proceeding, I report the most recent experimental results from BESIII about the XYZ sates. Two new X(3872) decay modes are observed, which is X(3872) → ωJ/ψ and X(3872) → π0χc1(1P). Precise measurement of cross sections of various channels reveal

New physics searches at the BESIII experiment. [PDF]

open access: yesNatl Sci Rev, 2021
Abstract The standard model (SM) of particle physics, comprised of the unified electroweak and quantum chromodynamic theories, accurately explains almost all experimental results related to the micro-world, and has made a number of predictions for previously unseen particles, most notably the Higgs scalar boson, that were subsequently ...

Charmonium and charmoniumlike states at the BESIII experiment. [PDF]

open access: yesNatl Sci Rev, 2021
Abstract Charmonium is a bound state of a charmed quark and a charmed antiquark, and a charmoniumlike state is a resonant structure that contains a charmed quark and antiquark pair but has properties that are incompatible with a conventional charmonium state.

Calculation of Binding Energy and Wave Function for Exotic Hidden‐Charm Pentaquark

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
In this study, pentaquark Pc(4380) composed of a baryon Σc, and a D¯∗ meson is considered. Pentaquark is as a bound state of two‐body systems composed of a baryon and a meson. The calculated potential will be expanded and replaced in the Schrödinger equation until tenth sentences of expansion.

The BESIII physics programme [PDF]

open access: yesNature Reviews Physics, 2019
The standard model of particle physics is a well-tested theoretical framework, but there are still a number of issues that deserve further experimental and theoretical investigation. For quark physics, such questions include: the nature of quark confinement, the mechanism that connects the quarks and gluons of the standard model theory to the strongly ...
