Marcus Chown takes familiar features of the everyday world and shows us, with breathtaking clarity, wit, and suspense, how they can be used to explain profound truths about the ultimate nature of reality. This is an essential cosmology primer for anyone curious about their surroundings and their place in the universe.
Only science writers of a very high calibre could achieve such compression. Marcus Chown - 'the finest cosmology writer of our day' (Matt Ridley) - has known the Dutch writer Govert Schilling for twenty years. Schilling pioneered this very swift form of explanation in a Dutch newspaper, and suggested to Chown that they collaborate on bringing it to a wider audience. Tweeting the Universe is unlike any other science book.
But how and when did this occur? In The Mystery of the Missing Antimatter, Helen Quinn and Yossi Nir guide readers into the very heart of this mystery—and along the way offer an exhilarating grand tour of cutting-edge physics.
This proceedings volume comprises papers written by the invited speakers discussing the many important issues of the new physics to be discovered at the Large Hadron Collider.
The basic interactions are described by gauge theories. These theories are discussed in detail, in particular the gauge theories of quantum electrodynamics (QED) and of quantum chromodynamics (QCD), based on the gauge group SU(3). In both theories the gauge bosons, the photon and the gluons, have no mass. The gauge theory of the electroweak interactions, based on the gauge group SU(2) x U(1), describes both the electromagnetic and the weak interactions. The weak force is generated by the exchange of the weak bosons. They have a large mass, and one believes that these masses are generated by a spontaneous breaking of the gauge symmetry.
It might be that the strong and the electroweak interactions are unified at very high energies ("Grand Unification"). The gauge groups SU(3) and SU(2) x U(1) must be subgroups of a big gauge group, describing the Grand Unification. Two such theories are discussed, based on the gauge groups SU(5) and SO(10).
In this volume are the lectures, given by the speakers at the conference on cosmology and particle physics. The discussed topics range from gravitational waves to cosmology, dark matter, dark energy and particle physics beyond the Standard Theory.
