Proof of principle for nucleon polarization measurement at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +754

A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using $10.09 \times 1 0^{9}$ $J / I ¨ $ events at BESIII, the…

First measurement of $I^£^{+} n \to I^ p$ and $I^£^{+} n \to I^£^{0} p$ cross sections via $I^£^{+}$ -nucleus scattering at an electron-positron collider

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Using $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / I ¨ $ events collected with the BESIII detector at the BEPCII storage ring, the reactions $I^£^{+} n \to I^ p$ and $Î£^{+}n\rightarrowÎ£^…

Observation of $I ¨ _{c J} (J = 0, 1, 2) \to p p ˉ I^\cdot I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $I ¨ (3686)$ events collected by the BESIII detector operating at the BEPCII storage ring, the decays $I ¨ _{c J} (J = 0, 1, 2) \to p p ˉ I^\cdot I^\cdot$ are…

Study of $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events accumulated with the BESIII detector, we analyze the decays $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$ ( $l = e$ or $I^¼$ ) via the process…

Search for a dark baryon in the $I^^{-} \to I ¨ ^{-} + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

A search for a dark baryon is performed for the first time in the two-body decay $I^^{-} \to I ¨ ^{-} + invisible$ using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / I ¨ $ events collected…

The LHAASO collabration, Zhen Cao, F. Aharonian +310

We report the discovery of an extended very-high-energy (VHE) gamma-ray source around the location of the middle-aged (207.8 kyr) pulsar PSR J0622+3749 with the Large High Altitude…
