   …motivating a possible interpretation by Lee, Takahashi, and Tsai involving the production of an invisible baryon-number-two scalar with a mass near $1.85$ GeV. Motivated by this hypothetical scenario, we investigate…

   We study quark matter at high isospin asymmetry in the limit of vanishing baryon density, a state of matter governed by the condensation of charged pions. In the weak-coupling limit,…
