A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons, mesons are composed of quarks bound together by the strong nuclear force.

Vapor pressure and saturated liquid density for HFO–1234ze(E) and HFO–1234ze(Z) were measured in the temperature range from 300 to 400 K by using the extraction method. Experimental uncertainties are ...
