Measurement of the cosmic ray nickel energy spectrum from 10 GeV/n to 2 TeV/n with the DAMPE

F. Alemanno, Q. An, P. Azzarello +144

Nickel, one of the most tightly bound nuclei alongside iron, is the most abundant heavy element beyond iron in cosmic rays. With DAMPE's excellent charge resolution and broad energ…

Search for the charmonium weak decay $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +720

We search for the weak decays $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ for the first time. The search is based on $(2712.4 \pm 14.3) \times 1 0^{6}$ events containin…

First Amplitude Analysis of $D^{0} \to K^{-} I ¨ ^{0} e^{+} I^½_{e}$ and Observation of $D^{0} \to K_{2}^{*} (1430)^{-} e^{+} I^½_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +687

We present the first amplitude analysis of the semileptonic decay $D^{0} \to K^{-} I ¨ ^{0} e^{+} I^½_{e}$ by analyzing $e^{+} e^{-}$ annihilation data corresponding to an integrated luminosity of…
