Topological Phase Transition in a Magnetic Weyl Semimetal

D. F. Liu, Q. N. Xu, E. K. Liu +15

Topological Weyl semimetals (TWSs) are exotic crystals possessing emergent relativistic Weyl fermions connected by unique surface Fermi-arcs (SFAs) in their electronic structures.…

Direct observation of the spin-orbit coupling effect in Magnetic Weyl semimetal Co3Sn2S2

D. F. Liu, E. K. Liu, Q. N. Xu +14

The spin-orbit coupling (SOC) lifts the band degeneracy that plays a vital role in the search for different topological states, such as topological insulators (TIs) and topological…

Magnetic Weyl Semimetal Phase in a Kagome Crystal

D. F. Liu, A. J. Liang, E. K. Liu +16

Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with…

Study of $η (1475)$ and $X (1835)$ in radiative $J / ψ$ decays to $γ ϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +428

The decay $J / ψ \to γ γ ϕ$ is studied using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector. Two structures around 1475 MeV/c $^{2}$ and 1835 MeV/c…

Search for a strangeonium-like structure $Z_{s}$ decaying into $ϕ π$ and a measurement of the cross section $e^{+} e^{-} \to ϕ π π$

M. Ablikim, M. N. Achasov, S. Ahmed +432

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 108 pb $^{- 1}$ collected with the BESIII detector at a center-of-mass energy of 2.125 GeV…

Observation of $e^{+} e^{-} \to ϕ χ_{c 1}$ and $ϕ χ_{c 2}$ at $s$ =4.600 GeV

M. Ablikim, M. N. Achasov, S. Ahmed +427

Using a data sample collected with the BESIII detector operating at the BEPCII storage ring at a center-of-mass energy of $s = 4.600$ GeV, we search for the production of $e^{…
