A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, γpp→pp+Z/γ+X, in proton-tagged events from proton–proton collisions at �=13TeV, recorded ...

We describe the Stiefel–Whitney classes (SWCs) of orthogonal representations 𝜋 of the finite special linear groups G=SL(2,Fq)

It was presumed that semimetallic bismuth (Bi) would not show superconductivity (SC) even at ultralow temperatures (<10 mK) due to its very low carrier density (≈3×1017cm−3). Recently, we have established bulk superconductivity ...

A search for the lepton-flavor violating decay of the Higgs boson and potential additional Higgs bosons with a mass in the range 110–160 GeV to an e±μ∓ pair is presented. The search is performed with a proton-proton collision ...

We present small-scale structure constraints on sterile dark matter produced from a heavy mediator particle, inspired by models of moduli decay. Dark matter particles produced through this mechanism can contribute to the ...

The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the previous GWTC-2.1, we present candidate ...

We consider a generic four-stroke quantum Otto engine consisting of two unitary and two thermalization strokes with an arbitrary many-body working medium. Using the Schwinger-Keldysh nonequilibrium Green's function formalism, ...

We study a system of equal-size circular disks, each with an asymmetrically placed pivot at a fixed distance from the center. The pivots are fixed at the vertices of a regular triangular lattice. The disks can rotate freely ...

Study of dynamical systems using partial state observation is an important problem due to its applicability to many real-world systems. We address the problem by studying an echo state network (ESN) framework with partial ...

Long-lived singlet states (LLSs) of nuclear spin pairs have been extensively studied and utilized in the isotropic phase via liquid-state nuclear magnetic resonance. However, there are hardly any reports of LLSs in the ...
