Observation of $D_{s}^{+} \to a_{0} (980)^{+} f_{0} (500)$ in the Amplitude Analysis of $D_{s}^{+} \to π^{+} π^{0} π^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +716

We report the first observation of the decay $D_{s}^{+} \to π^{+} π^{0} π^{0} η$ in a data set corresponding to an integrated luminosity of 7.33 fb $^{- 1}$ , collected in $e^{+} e^{-}$ collisions by t…

Positivity in the Renormalization of Effective Field Theory

You-Peng Liao, Jasper Roosmale Nepveu, Chia-Hsien Shen

We show that the direction of renormalization in effective field theory is constrained by fundamental principles in the infrared$\unicode{x2014}$unitarity, analyticity, and Lorentz…
