Abstract

Correction to one figure and the corresponding numbers in the text are noted for the paper. A wrong cross-section was used for the theory prediction of t¯tA(→ t¯t), which was estimated to differ by around 1% with respect to the one of t¯tH(→ t¯t). It was found later that the production cross-section for t¯tA(→ t¯t) can be up to 60% higher than the one of t¯tH(→ t¯t) for tan β ∼ 1. This affects the theoretical prediction shown in figure 7, and the limits in the tan β vs mH/A plane shown in figure 8(a). The changes in the text are noted for sections 8 and 9. • In the scenario where the scalar H and pseudo-scalar A bosons have equal masses and both contribute to BSM t¯tt¯t production, values of tan β below 1.9 and 0.7 are excluded for mH/A between 400 GeV and 1000 GeV, respectively, at 95% CL instead of 1.6 and 0.6. • In the scenario where only the pseudo-scalar A boson contributes to BSM t¯tt¯t production, values of tan β below 1.5 and 0.5 are excluded for mA between 400 GeV and 1000 GeV, respectively, at 95% CL instead of 1.2 and 0.5. The original plot for this scenario is not included in the paper as it was nearly identical to the one where only the scalar H boson contributes to BSM t¯tt¯t production, and was therefore omitted. After correction, the updated limits in the tan β vs mA plane are shown in figure 8(c). © 2025 Elsevier B.V., All rights reserved.
