The impact of EDGES 21cm data on dark matter interactions
/ Cheung, Kingman ; Kuo, JuiLin ; Ng, KinWang ; Tsai, YueLin Sming
The recently announced results on the 21cm absorption spectrum by the EDGES experiment can place very stringent limits on dark matter annihilation cross sections. [...]

Potential for probing threebody decays of LongLived Particles with MATHUSLA
/ Ibarra, Alejandro ; Molinaro, Emiliano ; Vogl, Stefan
Several extensions of the Standard Model predict the existence of LongLived Neutral Particles (LLNPs) with masses in the multiGeV range and decay lengths of O(100m) or longer. [...]

Generalized Pauli–Gursey transformation and Majorana neutrinos
/ Fujikawa, Kazuo
We discuss a generalization of the Pauli–Gursey transformation, which is motivated by the Autonne–Takagi factorization, to an arbitrary n number of generations of neutrinos using U(2n) that defines general canonical transformations and diagonalizes symmetric complex Majorana mass matrices in special cases. [...]
