Beyond the cosmological standard model [PDF]
Physics Reports, 2015 After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond , or smooth dark energy, often called modified gravity, has led to broader insights into a path forward, and a host of observational and experimental tests have ...

Higgs couplings beyond the standard model [PDF]
Journal of High Energy Physics, 2013 Abstract We consider the Higgs boson decay processes and its production, and provide a parameterisation tailored for testing models of new physics beyond the Standard Model. We also compare our formalism to other existing parameterisations based on scaling factors in front of the couplings and to effective Lagrangian approaches ...

PRESYMMETRY BEYOND THE STANDARD MODEL [PDF]
Modern Physics Letters A, 2009 We go beyond the Standard Model guided by presymmetry, the discrete electroweak quark–lepton symmetry hidden by topological effects which explain quark fractional charges as in condensed matter physics. We show that partners of the particles of the Standard Model and the discrete symmetry associated with this partnership appear as manifestations of a ...

Beyond the Standard Model [PDF]
Physics of Atomic Nuclei, 1995 The attempts to develop models beyond the Standard Model are briefly reviewed paying particular regard to the mechanisms responsible for symmetry breaking and mass generation. A comparison is made of the theoretical expectations with recent precision measurements for theories with composite Higgs and for supersymmetric theories with elementary Higgs ...

Physics beyond the standard model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2000 The Standard Model is in good shape, apart possibly from g_μ- 2 and some niggling doubts about the electroweak data. Something like a Higgs boson is required to provide particle masses, but theorists are actively considering alternatives. The problems of flavour, unification and quantum gravity will require physics beyond the Standard Model, and ...

, 2010 Six major frameworks have emerged attempting to describe particle physics beyond the Standard Model. Despite their different theoretical genera, these frameworks have a number of common phenomenological features and problems. While it will be possible (and desirable) to conduct model-independent searches for new physics at the LHC, it is equally ...
