Search for non-resonant production of semi-visible jets using Run 2 data in ATLAS
(Elsevier, 2024-01) -
Precision e- beam polarimetry at an e+e- B factory using tau-pair events

Search for B mesogenesis at B a B ar
(2023-05-01)A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the Universe. This scenario predicts exotic B-meson decays into a baryon and a dark-sector ... -
Search for a new pseudoscalar decaying into a pair of muons in events with a top-quark pair at s=13 TeV with the ATLAS detector

Comparison of inclusive and photon-tagged jet suppression in 5.02 TeV Pb+Pb collisions with ATLAS
(2023-11-10)Parton energy loss in the quark–gluon plasma (QGP) is studied with a measurement of photon-tagged jet production in 1.7 nb−1 of Pb+Pb data and 260 pb−1 of pp data, both at sNN=5.02 TeV, with the ATLAS detector. The process ... -
Search for Evidence of Baryogenesis and Dark Matter in B^{+}→ψ_{D}+p Decays at BABAR.
(2023-11-17)A new dark sector antibaryon, denoted ψ_{D}, could be produced in decays of B mesons. This Letter presents a search for B^{+}→ψ_{D}+p (and the charge conjugate) decays in e^{+}e^{-} annihilations at 10.58 GeV, using data ... -
Photoevaporation obfuscates the distinction between wind and viscous angular momentum transport in protoplanetary discs
(2024-01-01)How protoplanetary discs evolve remains an unanswered question. Competing theories of viscosity and magnetohydrodynamic disc winds have been put forward as the drivers of angular momentum transport in protoplanetary discs. ... -
Luminosity determination in pp collisions at √s=13 TeV using the ATLAS detector at the LHC
(2023-10-01)The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented, with pp collisions at a centre-of-mass energy s=13 TeV. The absolute luminosity scale is determined using van der Meer beam separation ... -
Observation of the γγ→ττ Process in Pb+Pb Collisions and Constraints on the τ-Lepton Anomalous Magnetic Moment with the ATLAS Detector.
(2023-10-13)This Letter reports the observation of τ-lepton-pair production in ultraperipheral lead-lead collisions Pb+Pb→Pb(γγ→ττ)Pb and constraints on the τ-lepton anomalous magnetic moment a_{τ}. The dataset corresponds to an ... -
Integrated and differential fiducial cross-section measurements for the vector boson fusion production of the Higgs boson in the Formula Presented decay channel at 13 TeV with the ATLAS detector
(2023-10-01)The vector-boson production cross section for the Higgs boson decay in the Formula Presented channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well ...
