Available in PDF, EPUB and Kindle. Book excerpt: We examine the constraints on the two Higgs doublet model (2HDM) due to the stability of the scalar potential and absence of Landau poles at energy scales below the Planck scale. We employ the most general 2HDM that incorporates an approximately Standard Model (SM) Higgs boson with a flavor-aligned Yukawa sector to eliminate potential tree-level Higgs-mediated flavor-changing neutral currents. Using basis independent techniques, we exhibit regimes of the 2HDM parameter space with a 125 GeV SM-like Higgs boson that is stable and perturbative up to the Planck scale. Implications for the heavy scalar spectrum are exhibited.

Download or read book Perspectives On Higgs Physics Ii written by Gordon Kane and published by World Scientific. This book was released on 1997-12-04 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model of particle physics is extremely successful in describing nature. It is, however, incomplete in one major way: the masses of gauge bosons and fermions enter the Standard Model through the Higgs mechanism. That is completely satisfactory technically, but it is not understood physically. We do not yet know what nature really does to give mass to particles. Understanding Higgs physics is necessary in order to complete the Standard Model, and to learn how to extend it and improve its foundations.This book is a collection of current work and thinking about these questions by active workers. It speculates about what form the answers will take, as well as updates and extends previous books and reviews. Some chapters emphasize theoretical questions, some focus on connections with other areas of physics, and some discuss how we can get data to uncover nature's solution. This second edition adds information and insights from the last five years, including the recent indirect but statistically significant evidence for the existence of a Higgs boson from precision measurements. It contains contributions from Blondel, Quiros, Haber, Pokorski, Dawson, Janot, Mrenna, Gunion, Ibanez, Ross, Bigi, Carena, Wagner, Georgi, Chanowitz, Yuan, Hill, and others.

Download or read book Supersymmetric Renormalisation Group Fixed Points and Third Generation Fermion Mass Predictions written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a supersymmetric renormalization group fixed point determination of the third generation fermion masses, in which the large mass ratio between the top and bottom quarks is attributed to a hierarchy in the vacuum expectation values of the two Higgs doublets. Above a supersymmetry breaking scale, M[sub s], we use the minimal supersymmetric standard model with a transition at M[sub s] to the standard model with only one Higgs- doublet effective. The mass predictions result from renormalization group evolution of large Yukawa couplings at M[sub x] [approximately] 1016 GeV. Averaging over a wide range of these couplings, not subject to any symmetry requirements, gives m[sub t] = 184.3[plus-minus]6.8 GeV, m[sub b] = 4.07[plus-minus]0.33 GeV, m[sub [tau]] = 1.78[plus-minus]0.33 GeV and a light Higgs mass m[sub h]o = 121.8[plus-minus]4.3 GeV for M[sub s] = 1 TeV and [alpha][sub s] (M[sub z]) = 0.125.

Download or read book Implications of the LHC Two photon Signal for Two Higgs doublet Models written by and published by . This book was released on 2012 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the implications for Two Higgs Doublet Models of the recent announcement at the LHC giving a tantalizing hint for a Higgs boson of mass 125 GeV decaying into two photons. We require that the experimental result be within a factor of two of the theoretical Standard Model prediction, and analyze the type I and type II models as well as the lepton-specific and flipped models, subject to this requirement. It is assumed that there is no new physics other than two Higgs doublets. In all of the models, we display the allowed region of parameter space taking the recent LHC announcement at face value, and we analyze the WW−, ZZ, {bar b}b and?+?− expectations in these allowed regions. Throughout the entire range of parameter space allowed by the?? constraint, the number of events for Higgs decays into WW, ZZ and b{bar b} are not changed from the Standard Model by more than a factor of two. In contrast, in the Lepton Specific model, decays to?+?− are very sensitive across the entire??-allowed region.

Download or read book The Standard Model and Beyond written by Paul Langacker and published by CRC Press. This book was released on 2009-12-01 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model and Beyond presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology. The book first reviews calculational techniques in field theory and the status of quantum electrodynamics. It then focuses on global and local symmetries and the construction of non-abelian gauge theories, before explaining the structure and tests of quantum chromodynamics. The book also describes the electroweak interactions and theory, including neutrino masses. The final chapter discusses the motivations for extending the standard model and examines supersymmetry, extended gauge groups, and grand unification. Thoroughly covering gauge field theories, symmetries, and topics beyond the standard model, this text equips readers with the tools to understand the structure and phenomenological consequences of the standard model, to construct extensions, and to perform calculations at tree level. It establishes the necessary background for readers to carry out more advanced research in particle physics. Supplementary materials are provided on the author’s website and a solutions manual is available for qualifying instructors.
