Resumo
Considerando diversas assimetrias esquerda-direita (left-right) estudamos a capacidade de colisores lépton-lépton na busca de novos bósons exóticos. Especificamente estudamos os efeitos de um bóson de gauge duplamente carregado, escalares duplamente carregados e de um bóson de gauge neutro extra que aparecem num modelo ‘SU(3) IND. C’ x ‘SU(3) IND. L’ x ‘(1) IND. N’. Os cálculos das assimetrias serão feitos para os seguintes processos e-e- —> e-e-, µ-µ- —> µ-µ- e e-µ- —> e-µ- e mostraremos que as assimetrias são sensíveis aos novos bósons de gauge mas são insensíveis aos escalares. Os resultados, principalmente os dos escalares duplamente carregados e do bóson vetorial neutro extra, podem ser interpretados independentemente do modelo. Também iremos apresentar a construção supersimétrica de um dos modelos com simetria ‘SU(3) IND. C’ x ‘SU(3) IND. L’ x ‘(1) IND. N’ no final
By considering left-right asymmetries we study the capabilities of lepton-lepton colliders in searching for new exotic vector bosons. Specifically we study the effect of a doubly charged bilepton boson, a double charged scalar and an extra neutral vector boson appearing in a ‘SU(3) IND. C’ x ‘SU(3) IND. L’ x ‘(1) IND. N’ model. The calculations to the asymmetries are doing for the processes e-e- —> e-e-, µ-µ- —> µ-µ- and e-µ- —> e-µ- and show that these asymmetries are very sensitive to new gauge bosons but they are insensitive to scalar ones. Our results, mainly of the scalars and the extra neutral vector boson part can be interpreted in a model independent way. We will present also the construction of the supersymmetric version of the model with symmetry ‘SU(3) IND. C’ x ‘SU(3) IND. L’ x ‘(1) IND. N’ at the end
