    The CMS Collaboration (2022)
    A search is reported for high-mass hadronic resonances that decay to a parton and a Lorentz-boosted resonance, which in turn decays into a pair of partons. The search is based on data collected with the CMS detector at the LHC in proton-proton collisions at s=13TeV, corresponding to an integrated luminosity of 138fb−1. The boosted resonance is ...
  • The role of spatial structures of tissues in cancer initiation dynamics 

    Spaulding, Cade; Teimouri, Hamid; Kolomeisky, Anatoly B.; Center for Theoretical Biological Physics (2022)
    It is widely believed that biological tissues evolved to lower the risks of cancer development. One of the specific ways to minimize the chances of tumor formation comes from proper spatial organization of tissues. However, the microscopic mechanisms of underlying processes remain not fully understood. We present a theoretical investigation on the ...

    Jin, Shikai; Bueno, Carlos; Lu, Wei; Wang, Qian; Chen, Mingchen; (2022)
    Bacteriophage T7 gp4 helicase has served as a model system for understanding mechanisms of hexameric replicative helicase translocation. The mechanistic basis of how nucleoside 5′-triphosphate hydrolysis and translocation of gp4 helicase are coupled is not fully resolved. Here, we used a thermodynamically benchmarked coarse-grained protein force ...
  • Stochastic fluctuations promote ordered pattern formation of cells in the Notch-Delta signaling pathway 

    Galbraith, Madeline; Bocci, Federico; Onuchic, José N.; Center for Theoretical Biological Physics (2022)
    The Notch-Delta signaling pathway mediates cell differentiation implicated in many regulatory processes including spatiotemporal patterning in tissues by promoting alternate cell fates between neighboring cells. At the multicellular level, this "lateral inhibition” principle leads to checkerboard patterns with alternation of Sender and Receiver cells. ...
  • Identification of hadronic tau lepton decays using a deep neural network 

    The CMS collaboration (2022)
    A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (τh) that originate from genuine tau leptons in the CMS detector against τh candidates that originate from quark or gluon jets, electrons, or muons. The algorithm inputs information from all reconstructed particles in the vicinity of a τh candidate and employs ...

  • Improving the Low-energy Transient Sensitivity of AMEGO-X using Single-site Events 

    Martinez-Castellanos, I.; Fleischhack, Henrike; Karwin, C.; Negro, M.; Tak, D.; (2022)
    AMEGO-X, the All-sky Medium Energy Gamma-ray Observatory eXplorer, is a proposed instrument designed to bridge the so-called "MeV gap" by surveying the sky with unprecedented sensitivity from ∼100 keV to about 1 GeV. This energy band is of key importance for multimessenger and multiwavelength studies but it is nevertheless currently underexplored. ...
  • Probing Charm Quark Dynamics via Multiparticle Correlations in Pb-Pb Collisions at √sNN=5.02 TeV 

    CMS Collaboration (2022)
    Multiparticle azimuthal correlations of prompt D0 mesons are measured in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of √sNN=5.02 TeV. For the first time, a four-particle cumulant method is used to extract the second Fourier coefficient of the azimuthal distribution (v2) of D0 mesons as a function of event centrality and the D0 ...
  • Chemical and Physical Characterization of the Isolated Protostellar Source CB68: FAUST IV 

    Imai, Muneaki; Oya, Yoko; Svoboda, Brian; Liu, Hauyu Baobab; Lefloch, Bertrand; (2022)
    The chemical diversity of low-mass protostellar sources has so far been recognized, and environmental effects are invoked as its origin. In this context, observations of isolated protostellar sources without the influence of nearby objects are of particular importance. Here, we report the chemical and physical structures of the low-mass Class 0 ...
  • K-point longitudinal acoustic phonons are responsible for ultrafast intervalley scattering in monolayer MoSe2 

    Bae, Soungmin; Matsumoto, Kana; Raebiger, Hannes; Shudo, Ken-ichi; Kim, Yong-Hoon; (2022)
    In transition metal dichalcogenides, valley depolarization through intervalley carrier scattering by zone-edge phonons is often unavoidable. Although valley depolarization processes related to various acoustic phonons have been suggested, their optical verification is still vague due to nearly degenerate phonon frequencies on acoustic phonon branches ...
  • Anisotropic magnon damping by zero-temperature quantum fluctuations in ferromagnetic CrGeTe3 

    Chen, Lebing; Mao, Chengjie; Chung, Jae-Ho; Stone, Matthew B.; Kolesnikov, Alexander I.; (2022)
    Spin and lattice are two fundamental degrees of freedom in a solid, and their fluctuations about the equilibrium values in a magnetic ordered crystalline lattice form quasiparticles termed magnons (spin waves) and phonons (lattice waves), respectively. In most materials with strong spin-lattice coupling (SLC), the interaction of spin and lattice ...

  • Geodesic geometry of 2+1-D Dirac materials subject to artificial, quenched gravitational singularities 

    Davis, Seth; Foster, Matthew; Rice Center for Quantum Materials (2022)
    The spatial modulation of the Fermi velocity for gapless Dirac electrons in quantum materials is mathematically equivalent to the problem of massless fermions on a certain class of curved spacetime manifolds. We study null geodesic lensing through these manifolds, which are dominated by curvature singularities, such as nematic singularity walls (where ...
