Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the $e^+e^- to K_{S}^{0}K^{pm}pi^{mp}$ Born cross sections at center-of-mass energies between 3.8 and 4.6,GeV, corresponding to a luminosity of about 5.0~fb$^{-1}$. The results are compatible with the BABAR measurements, but with the precision significantly improved. A simple $1/s^n$ dependence for the continuum process can describe the measured cross sections, but a better fit is obtained by an additional resonance near 4.2,GeV, which could be an excited charmonium or a charmonium-like state.

Using $5.2 mathrm{fb}^{-1}$ $e^+ e^-$ annihilation data samples collected with the BESIII detector, we measure the cross sections of $e^+e^- to K_S^0 K^pm pi^mp pi^0$ and $K_{S}^{0}K^{pm}pi^{mp}eta$ at center-of-mass energies from $3.90$ to $4.60$ G
eV. In addition, we search for the charmonium-like resonance $Y(4260)$ decays into $K_{S}^{0}K^{pm}pi^{mp}pi^0$ and $K_{S}^{0}K^{pm}pi^{mp}eta$, and $Z_c^{0,pm}(3900)$ decays into $K_{S}^{0}K^{pm}pi^{mp,0}$ and $K_{S}^{0}K^{pm}eta$. Corresponding upper limits are provided since no clear signal is observed.
Using data taken at 23 center-of-mass energies between 4.0 and 4.6 GeV with the BESIII detector at the BEPCII collider and with a total integrated luminosity of approximately $15$ fb$^{-1}$, the process $e^+e^-to 2(p bar{p})$ is studied for the first
time. The Born cross sections for $e^+e^-to 2(p bar{p})$ are measured, and no significant structure is observed in the lineshape. The baryon pair ($pp$ and $bar{p}bar{p}$) invariant mass spectra are consistent with phase space, therefore no hexaquark or di-baryon state is found.
Based on $e^+e^-$ annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center of mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of $e^{+}e^{-}rightarrow p bar{p} pi^{0}$ are performe
d. No significant resonant structure is observed in the measured energy-dependent cross section. The upper limit on the Born cross section of $e^{+}e^{-}rightarrow Y(4260) rightarrow p bar{p} pi^{0}$ at the 90% C.L. is determined to be 0.01 pb.
Based on $14.7~textrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected with the BESIII detector at the BEPCII collider at 17 different center-of-mass energies between $3.7730~textrm{GeV}$ and $4.5995~textrm{GeV}$, Born cross sections of the two proc
esses $e^+e^- to pbar{p}eta$ and $e^+e^- to pbar{p}omega$ are measured for the first time. No indication of resonant production through a vector state $V$ is observed, and upper limits on the Born cross sections of $e^+e^- to V to pbar{p}eta$ and $e^+e^- to V to pbar{p}omega$ at the $90%$ confidence level are calculated for a large parameter space in resonance masses and widths. For the current world average parameters of the $psi(4230)$ of $m=4.2187~textrm{GeV}/c^{2}$ and $Gamma=44~textrm{MeV}$, we find upper limits on resonant production of the $pbar{p}eta$ and $pbar{p}omega$ final states of $7.5~textrm{pb}$ and $10.4~textrm{pb}$ at the $90%$ CL, respectively.
