The Hot QCD White Paper:
... The discoveries of the past decade have posed or sharpened questions that are central
to understanding the nature, structure, and origin of the hottest liquid form of matter
that the universe has ever seen. As our highest priority we recommend a program to
complete the search for the critical point ...
Experiments and theory in cold and ultracold collisions
... only because of their importance to these new areas of
atomic, molecular, and optical physics but also because
their investigation has lead to new insights into how cold
collision spectroscopy can lead to precision measurements of atomic and molecular parameters and how radiation fields can manipula ...
Cold and trapped metastable noble gases
... has been expanding ever since. It started as a subfield of
atomic physics and now extends to other domains such

... Golden Opportunity to Understand Matter versus Antimatter?
The SM with massive Majorana neutrinos accommodates five irreducible
CP-invariance violating phases.
• One is the phase in the CKM phase. We have measured it, it is large,
and we don’t understand its value. At all.
• One is θQCD term (θGG̃). ...

... • Mechanical waves are waves which propagate through a material medium
at a wave speed which depends on the elastic and inertial properties of that
• There are two basic types of wave motion for mechanical waves:
longitudinal waves and transverse waves.
In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges, as well as other particle properties such as lepton and baryon numbers and quantum spin. Collisions between particles and antiparticles lead to the annihilation of both, giving rise to variable proportions of intense photons (gamma rays), neutrinos, and less massive particle–antiparticle pairs. The total consequence of annihilation is a release of energy available for work, proportional to the total matter and antimatter mass, in accord with the mass–energy equivalence equation, E = mc2.Antiparticles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements. Studies of cosmic rays have identified both positrons and antiprotons, presumably produced by collisions between particles of ordinary matter. Satellite-based searches of cosmic rays for antideuteron and antihelium particles have yielded nothing. There is considerable speculation as to why the observable universe is composed almost entirely of ordinary matter, as opposed to a more even mixture of matter and antimatter. This asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. The process by which this inequality between particles and antiparticles developed is called baryogenesis.Antimatter in the form of anti-atoms is one of the most difficult materials to produce. Antimatter in the form of individual anti-particles, however, is commonly produced by particle accelerators and in some types of radioactive decay. The nuclei of antihelium (both helium-3 and helium-4) have been artificially produced with difficulty. These are the most complex anti-nuclei so far observed.
