The precise measurement of the spectrum protons, most abundant component cosmic radiation, is necessary to understand source and acceleration rays in Milky Way. This work reports ray proton fluxes with kinetic energies from 40 GeV 100 TeV, two a half years data recorded by DArk Matter Particle Explorer (DAMPE). first time an experiment directly measures protons up ~100 TeV high statistics. measured confirms spectral hardening found previous experiments reveals softening at ~13.6 index...
Using the latest AMS-02 cosmic ray antiproton flux data, we search for potential dark matter annihilation signal. The background parameters about propagation, source injection, and solar modulation are not assumed {\it a priori}, but based on results inferred from recent B/C ratio proton data measurements instead. possible signal is incorporated into model self-consistently under Bayesian framework. Compared with astrophysical only hypothesis, find that favored. rest mass of particles $\sim...
The measurement of the energy spectrum cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years data recorded by Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening observed at an about 1.3 TeV, similar previous observations. In addition, a spectral softening 34 revealed for first time with large statistics and well controlled systematic uncertainties, overall significance 4.3σ. DAMPE measurements both protons suggest particle charge dependent energy, although...
The diffuse Galactic γ-ray emission, mainly produced via interactions between cosmic rays and the interstellar medium and/or radiation field, is a very important probe of distribution, propagation, interaction in Milky Way. In this Letter, we report measurements γ from plane 10 TeV 1 PeV energies, with square kilometer array Large High Altitude Air Shower Observatory (LHAASO). Diffuse emissions inner (15°<l<125°, |b|<5°) outer (125°<l<235°, are detected 29.1σ 12.7σ significance,...
The origin of interstellar and intergalactic magnetic fields remains largely unknown. One possibility is that they are related to the primordial (PMFs) produced by, for instance, phase transitions early Universe. In this paper, PMF-induced turbulence generated at around QCD transition epoch---the characteristic field strength ${B}_{\mathrm{ch}}^{*}\ensuremath{\sim}\mathcal{O}(1)\text{ }\text{ }\mathrm{\ensuremath{\mu}}\mathrm{G}$ coherent length scale...
We present the measurements of all-particle energy spectrum and mean logarithmic mass cosmic rays in range 0.3-30 PeV using data collected from LHAASO-KM2A between September 2021 December 2022, which is based on a nearly composition-independent reconstruction method, achieving unprecedented accuracy. Our analysis reveals position knee at 3.67±0.05±0.15 PeV. Below knee, spectral index found to be -2.7413±0.0004±0.0050, while above it -3.128±0.005±0.027, with sharpness transition measured...
The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature dark matter and other new astrophysical phenomena, could be used with species to understand production propagation in Galaxy. For instance, low-energy antideuterons would provide a "smoking gun" signature annihilation or decay, essentially free background. Studies recent years have emphasized that models must considered together abundant cosmic antiprotons any potential observation...

Carbon dioxide cycloaddition into fine chemicals is prospective technology to solve energy crisis and environmental issues. However, high temperature pressure are usually required in the conventional reactions of CO2 with epoxides. Moreover, metal active sites play a vital role cycloaddition, but it still unclear. Herein, we select isostructural MOF-919-Cu-Fe MOF-919-Cu-Al as models promote performance clarify effects type on cycloaddition. The exposed Fe Cu Lewis acid reaches over 99.9%...
The XENON1T collaboration reported an excess of the low-energy electron recoil events between 1 and 7 keV. We explore possibility to explain such anomaly by MeV-scale dark matter (DM) heated interior Sun due same DM-electron interaction as in detector. kinetic energies DM particles can reach a few keV, potentially account for signals detected XENON1T. study different form factors interactions, $F(q)\propto q^i$ with $i=0,1,2$ $q$ being momentum exchange, find that all these cases inclusion...
For the newly discovered W-boson mass anomaly, one of simplest dark matter (DM) models that can account for anomaly without violating other astrophysical and experimental constraints is inert two Higgs doublet model, in which DM (m_{S}) found to be within ∼54-74 GeV. In this annihilation via SS→bb[over ¯] SS→WW^{*} would produce antiprotons gamma rays, may excesses identified previously both particles. Motivated by this, we reanalyze AMS-02 antiproton Fermi-LAT Galactic center γ-ray data....

A spectral softening at $\sim0.9$ TeV tentative peak $\sim1.4$ have been reported. We study physical implications DAMPE data this work. presence break significantly tightens constraints on model parameters to explain electron/positron excesses. can either be explained by maximum...
Recent observations of the light component cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to highest energies. The Dark Matter Particle Explorer is a satellite-based experiment has been operational since December 2015, continuously collecting data on high-energy cosmic particles with very good statistics, energy resolution, particle identification capabilities. In this work, latest proton+helium in range from 46 GeV 464 TeV are...

Abstract Identifying Galactic PeVatrons (PeV particle accelerators) from ultrahigh-energy (UHE, >100 TeV) γ -ray sources plays a crucial role in revealing the origin of cosmic rays. The UHE source 1LHAASO J1857+0203u is suggested to be associated with HESS J1858+020, which may attributed possible PeVatron candidate supernova remnant (SNR) G35.6−0.4 or H ii region G35.6−0.5. We perform detailed analysis on very-high-energy and emissions toward this data Large High Altitude Air Shower...
Precise direct cosmic-ray (CR) measurements provide an important probe to study the energetic particle sources in our Galaxy, and interstellar environment through which these particles propagate. Uncertainties on hadronic models, ion-nucleon cross sections particular, are currently limiting factor toward obtaining more accurate CR ion flux with calorimetric space-based experiments. We present energy-dependent measurement of inelastic section protons helium-4 nuclei (alpha particles) a...
Abstract Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse γ -rays detectable by arrays such LHAASO. These result from proton–proton (pp) collisions very or inverse Compton (IC) scattering positron-electron pairs created pγ interactions ultra-high-energy (UHECRs). We analyzed -ray emission Coma, Perseus, and Virgo using LHAASO data. Diffuse was modeled a disk radius R 500 for each cluster while...
