Exploring the Cosmic Dawn through the 21 cm Forest and High-redshift Radio Sources with the SKA

Junsong Cang, Benedetta Ciardi, Barun Maity +12

The 21~cm forest, seen as absorption features in the spectra of distant radio sources, is produced by intervening neutral hydrogen and offers a direct probe of the neutral intergal…

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…

Prospects for Observing High-redshift Radio-loud Quasars in the SKA Era: Paving the Way for 21-cm Forest Observations

Qi Niu, Yichao Li, Yidong Xu +2

The 21-cm forest is a sensitive probe for the early heating process and small-scale structures during the epoch of reionization (EoR), to be realized with the upcoming Square Kilom…
