About the Origins of the Supersymmetric Standard Model
نویسنده
چکیده
However many obstacles seemed, long ago, to prevent supersymmetry from possibly being a fundamental symmetry of Nature. Which fermions and bosons could be related ? Is spontaneous supersymmetry breaking possible at all ? If yes, where is the corresponding spin1 2 Goldstone fermion ? Supersymmetric theories also involve Majorana fermions, unknown in Nature. And how could we define conserved quantum numbers like B and L, when these are carried by fundamental (Dirac) fermions only, not by bosons ?

A Supersymmetry Primer
I provide a pedagogical introduction to supersymmetry. The level of discussion is aimed at readers who are familiar with the Standard Model and quantum field theory, but who have little or no prior exposure to supersymmetry. Topics covered include: motivations for supersymmetry; the construction of supersymmetric Lagrangians; supersymmetry-breaking interactions; the Minimal Supersymmetric Stand...
متن کاملAbout Superpartners and the Origins of the Supersymmetric Standard Model
We recall the obstacles which seemed, long ago, to prevent supersymmetry from possibly being a fundamental symmetry of Nature. Which bosons and fermions could be related ? Is spontaneous supersymmetry breaking possible ? Where is the spin1 2 Goldstone fermion of supersymmetry ? Can one define conserved baryon and lepton numbers in such theories, although they systematically involve self-conjuga...
متن کاملA Study on the Origins of Identification among the High-School Female Students in Khalkhal
This research studies the origins of identity among the female students in Khalkhal high-schools in 2012-2013. Data was gathered through the survey method (questionnaires) and the library method. The dependent variable was the study of identity seeking, but the independent variable includes the degree of religious orientation, social status of the family, the access to foreign networks, the sol...
متن کاملTowards the Development of a Socially-Informed, Process-Oriented Model of Research in Metadiscourse
Since the early development of interest in the interpersonal dimensions of academic communication in the 1980s, the analytic potentials of the concept of metadiscourse have motivated a large number of investigations. Although these analytic potentials have facilitated the study of diverse academic genres, there has always been a risk of detachment of textual analyses form the contextual origins...
متن کاملNeutralino Dark Matter from MSSM Flat Directions in light of WMAP Result
The minimal supersymmetric standard model (MSSM) has a truly supersymmetric way to explain both the baryon asymmetry and cold dark matter in the present Universe, that is, “Affleck–Dine baryo/DM-genesis.” The associated late-time decay of Q-balls directly connects the origins of the baryon asymmetry and dark matter, and also predicts a specific nature of the LSP. In this paper, we investigate t...
