CP violation or new physics?
(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. ...

Could 'Higgsogenesis' explain dark matter?
(Phys.org) —The recently discovered Higgs boson is best known for its important role in explaining particle mass. But now some physicists are wondering if the Higgs could have played an equally significant role in generating ...
Quark asymmetries hint at physics beyond the Standard Model
(Phys.org) —While scientists have become increasingly convinced that the Standard Model of particle physics is incomplete, it's still unclear exactly how the Standard Model needs to be extended. Experiments have shown that ...
Observations of early universe hint at a giant excess of anti-neutrinos
(Phys.org) —Scientists have a great deal of evidence to support the fact that the universe contains much more baryonic matter than baryonic anti-matter, a phenomenon known as baryon asymmetry. Baryons, which are defined ...
Physicists propose mechanism that explains the origins of both dark matter and 'normal' matter
(PhysOrg.com) -- Through precise cosmological measurements, scientists know that about 4.6% of the energy of the Universe is made of baryonic matter (normal atoms), about 23% is made of dark matter, and the remaining 72% ...
Could dark baryons explain dark matter?
(PhysOrg.com) -- "The prevailing belief about dark matter particles is that they should be about 100 or more times heavier than protons," Subir Sarkar tells PhysOrg.com. "However, we were thinking about the possibility of ...
Why does matter exist? Roundness of electrons may hold clues
In the first moments of our universe, countless numbers of protons, neutrons and electrons formed alongside their antimatter counterparts. As the universe expanded and cooled, almost all these matter and antimatter particles ...

Inertial confinement fusion implosions have significant 3-D asymmetries
Data correlating two factors that lead to implosion asymmetries have brought Lawrence Livermore National Laboratory (LLNL) scientists a step closer to understanding the gap between simulations and performance of inertial ...

How chromosomes 'cheat' for the chance to get into an egg
Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete—a sperm or an egg—each copy has a 50-50 shot at being passed on. ...
