Amplitude analysis of B s 0 → K S 0 K±π∓ decays [PDF]

open access: yes, 2019
The first untagged decay-time-integrated amplitude analysis of B0 s → K0 SK±π ∓ decays is performed using a sample corresponding to 3.0 fb−1 of pp collision data recorded with the LHCb detector during 2011 and 2012.

Search for a heavy neutral particle decaying into an electron and a muon using 1 fb−1 of ATLAS data

open access: yesEuropean Physical Journal C: Particles and Fields, 2011
A search is presented for a high mass neutral particle that decays directly to the e ± μ ∓ final state. The data sample was recorded by the ATLAS detector in $\sqrt{s}=7\mbox{~TeV}$ pp collisions at the LHC from March to June 2011 and corresponds to an ...

Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 7 TeV proton-proton collision data with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2012
A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, and at least one hadronically decaying τ lepton, with zero or one additional light lepton (e/μ), has been performed using 4.7 fb−1 of proton-proton collision data ...

Proof of principle for a light dark matter search with low-energy positron beams at NA64

open access: yesJournal of High Energy Physics
Thermal light dark matter (LDM) with particle masses in the 1 MeV–1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Universe.

First measurement of the CKM angle ϕ3 with B±→ D($ {K}_{\mathrm{S}}^0 $π+π−π0) K± decays

open access: yes, 2019
A bstract We present the first model-independent measurement of the CKM unitarity triangle angle ϕ 3 using B ± → D ( $ {K}_{\mathrm{S}}^0 $ K S 0 π + π − π 0 ) K ± decays, where D indicates either a D 0 or $ \overline{D} $ D ¯ 0 meson.
