Novel B-decay signatures of light scalars at high energy facilities Blance, Andrew Rodríguez Chala, Mikael Ramos, María Spannowsky, Michael We study the phenomenology of light scalars of masses m1 and m2 coupling to heavy flavor-violating vector bosons of mass mV. For m1;2 ≲ few GeV, this scenario triggers the rare B meson decays B0s → 3μþ3μ−, B0 → 3μþ3μ−, Bþ → Kþ3μþ3μ−, and B0s → K0 3μþ3μ−; the last two being the most important ones for m1 ∼ m2. None of these signals have been studied experimentally; therefore, we propose analyses to test these channels at the LHCb. We demonstrate that the reach of this facility extends to branching ratios as small as 6.0 × 10−9, 1.6 × 10−9, 5.9 × 10−9, and 1.8 × 10−8 for the aforementioned channels, respectively. For m1;2 ≫ O(1) GeV, we show that slightly modified versions of current multilepton and multitau searches at the LHC can probe wide regions of the parameter space of this scenario. Altogether, the potential of the searches we propose outperform other constraints such as those from meson mixing 2020-01-08T13:52:30Z 2020-01-08T13:52:30Z 2019-12-06 info:eu-repo/semantics/article Blance, A., Chala, M., Ramos, M., & Spannowsky, M.
