@article{10902/32896, year = {2023}, month = {7}, url = {https://hdl.handle.net/10902/32896}, abstract = {A search is reported for pairs of light Higgs bosons (H1) produced in supersymmetric cascade decays in final states with small missing transverse momentum. A dataset of LHC pp collisions collected with the CMS detector at √s = 13 TeV and corresponding to an integrated luminosity of 138 fb−¹ is used. The search targets events where both H1 bosons decay into b¯b pairs that are reconstructed as large-radius jets using substructure techniques. No evidence is found for an excess of events beyond the background expectations of the standard model (SM). Results from the search are interpreted in the next-to-minimal supersymmetric extension of the SM, where a "singlino" of small mass leads to squark and gluino cascade decays that can predominantly end in a highly Lorentz-boosted singlet-like H1 and a singlino-like neutralino of small transversemomentum. Upper limits are set on the product of the squark or gluino pair production cross section and the square of the b¯b branching fraction of the H1 in a benchmark model containing almost mass-degenerate gluinos and light-flavour squarks.Under the assumption of an SM-like H1 → b¯b branching fraction, H₁ bosons with masses in the range 40–120 GeV arising from the decays of squarks or gluinos with a mass of 1200–2500 GeV are excluded at 95% confidence level.}, publisher = {Springer New York LLC}, publisher = {European Physical Journal C, 2023, 83(7), 571}, title = {Search for light Higgs bosons from supersymmetric cascade decays in pp collisions at √s=13TeV}, author = {Tumasyan, A. and Brochero Cifuentes, Javier Andrés and Cabrillo Bartolomé, José Iban and Calderón Tazón, Alicia and Duarte Campderros, Jorge and Fernández García, Marcos and Fernández Madrazo, Celia and Fernández Manteca, Pedro José and García Alonso, Andrea and Gómez Gramuglio, Gervasio and Martínez Rivero, Celso and Martínez Ruiz del Árbol, Pablo and Matorras Weinig, Francisco and Matorras Cuevas, Pablo and Piedra Gómez, Jonatan and Prieëls, Cedric and Ruiz Jimeno, Alberto and Scodellaro, Luca and Vila Álvarez, Iván and Vizán García, Jesús Manuel}, }
