In this study,we perform a detailed analysis on the same-sign dilepton signature in the inert doublet model.Focusing on the low dark matter mass region,we randomly scan the corresponding parameter space.Viable samples allowed by various constraints are obtained,and among them are twenty benchmark points that are selected for further study on collider signature.At hadron colliders,the same-sign dilepton signature is produced via pp → W±*W±*jj → H±H±jj with the leptonic decay mode H± → HW±(→ l±v),where H represents the dark mat-ter candidate.We investigate the testability of this signal at the high-luminosity LHC (HL-LHC) and the proposed 27 TeV high-energy LHC (HE-LHC).According to our simulation,the HL-LHC with L =3 ab-1 can barely probe this signal.Meanwhile,for the HE-LHC with L=15ab-1,it is promising to obtain a 5σ significance when 250 GeV ≤ mH±-mH ≤ 300 GeV with dark matter mass mH ～ 60 or 71 GeV.

Neutrons tunneling to the classically forbidden (CF) region in the neutron-rich nucleus 68Ca are invest-igated in the Skyrme Hartree-Fock (HF) and Hartree-Fock-Bogoliubov (HFB) models.The definition of the CF re-gion is examined in the HF model by using d
In this paper,we explore the properties of holographic entanglement entropy (HEE),mutual information(MI) and entanglement of purification (EoP) in holographic Lifshitz theory.These informational quantities exhibit some universal properties of holographic
In this paper,we analyze the dependence of the topological charge density from the overlap operator on the Wilson mass parameter in the overlap kernel by the symmetric multi-probing source (SMP) method.We observe that non-trivial topological objects are r
The tensor-force effects on the evolution of spin-orbit splittings in neutron drops are investigated within the framework of the relativistic Hartree-Fock theory.For a fair comparison on the pure mean-field level,the results of the relativistic Brueckner-
We explore the effects of the density dependence of symmetry energy on the crust-core phase transition and dynamical instabilities in cold and warm neutron stars in the relativistic mean field (RMF) theory with point-coupling interactions using the Vlasov
Deep learning has been widely and actively used in various research areas.Recently,in gauge/gravity duality,a new deep learning technique called AdS/DL (Deep Learning) has been proposed.The goal of this paper is to explain the essence of AdS/DL in the sim
The two-photon-exchange (TPE) effect plays a key role in extracting the form factors (FFs) of the pro-ton.In this work,we discuss several exact properties of the TPE effect in the elastic ep scattering.By taking four low energy interactions as examples,we
The angle-differential cross sections of neutron-induced deuteron production from carbon were meas-ured at six neutron energies from 25 to 52 MeV relative to those of n-p elastic scattering at the China Spallation Neutron Source (CSNS) Back-n white neutro
Super-entropic black holes possess finite-area but noncompact event horizons and violate the reverse iso-perimetric inequality.It has been conjectured that such black holes always have negative specific heat at constant volume CV or negative specific heat
Measuring vector boson scattering (VBS) precisely is an important step toward understanding the elec-troweak symmetry breaking of and detecting new physics beyond the standard model (SM).Herein,we propose a neural network that compresses the features of t
