Higgs-pair production via gluon fusion at NLO QCD in the Standard Model and Beyond
2021
La fı́sica de las partı́culas elementales está bien descrita por el Modelo Estándar (SM, por sus siglas en inglés.). La presencia de la interacción electrodébil prohı́be los términos cuadráticos con respecto a los campos, i.e. términos de masa, en el Lagrangiano del SM. La presencia de tales términos de masa requieren de la llamada ruptura espontánea de la simetrı́a, introduciendo un doblete electrodébil con un valor esperado de vacı́o no nulo. Como recordatorio, la ruptura espontánea de la simetrı́a genera un bosón escalar neutro, el renombrado bosón de Higgs. Aunque fue predicho en los años 60 por argumentos teóricos, en el 2012 los experimentos del Large Hadron Collider (LHC), ATLAS y CM…

The cross section times BR(A->ZH) times BR(H->bb) limits for an A boson in the type-I, tanbeta 10, 2HDM. For each signal point, characterised by the mass pair (mA, mH), two limits are provided, the observed and the expected. The correct width as predicted by this particular parameter choice of the 2HDM is used. For type-I only gluon-gluon fusion is used and the nb=2 category only.
