The kilometer-square array (KM2A) of the Large High Altitude Air Shower Observatory (LHAASO, located at 4410 m above sea level with an atmospheric depth $600\text{ }\text{ }\mathrm{g}/{\mathrm{cm}}^{2}$) can simultaneously measure air shower sizes both electromagnetic particles and muon contents high precision for cosmic rays energies in knee region. An advantage LHAASO experiment is that it be performed maximum showers In this study, different methods to reconstruct ray energy are...
An electrochemical fingerprint-based methodology is described here for vinegar authentic identification. The commercial three-electrode system can be directly inserted into voltammetric profile recording without the addition of electrolyte. free amino acids and aroma compounds produced from fermentation process oxidized during differential pulse scan. fingerprint pattern varies between different brand due to raw ingredients process. DPV profiles converted 2D scatter patterns identifying...
Composition measurement of cosmic rays (CRs) around the knee CR energy spectrum is crucial for studying processes particle acceleration and propagation Galactic CRs. The Square Kilometer Array (KM2A) Large High Altitude Air Shower Observatory (LHAASO) can provide precise muonic electromagnetic (em) components in CR-induced extensive air showers, hence a good chance to disentangle composition. Here we propose an approach decomposing compositions with number ratio between muons em particles...
The attenuation length of the muon content in extensive air showers provides important information regarding generation and development showers. This can be used not only to improve description such but also test fundamental models hadronic interactions. Using data from LHAASO-KM2A experiment, high-energy was studied. measured experimental energy range 0.3 30 PeV using constant intensity cut method. By comparing with predictions interaction (QGSJET-II-04, SIBYLL 2.3d, EPOS-LHC), it is...

In the framework of Color Glass Condensate (CGC) effective field theory (EFT), we calculate two-gluon rapidity correlations in leading and sub-leading orders $p_\perp/Q_s$. order, both short- long-range are enhanced. contrast, contribution order is mainly short range quantum correlations. It much smaller than that one, but not negligible. Transverse momentum dependence correlation shows sensitive to saturation two incident particles, one not.
We investigate the azimuthal correlations of glasma in p-p collisions at $\sqrt{s_{\mathrm{NN}}}=7$ TeV by using CGC formalism. As expected, show two peaks $\Delta\phi=0$ and $\pi$ which represent collimation production CGC. Beyond that, fine structures, i.e. bumps or shoulders between peaks, when least one gluon has small $x$. The structures are demonstrated to be associated with saturation momentum, likely appear transverse momentum around $2Q_{\mathrm{sp}}=1.8$ GeV$/$c.

The number of muons observed at the ground from air showers is sensitive to mass composition cosmic ray. Large High Altitude Air Shower Observatory a hybrid extensive shower array and KM2A sub-array covering an area 1 km$^2$, consisting electromagnetic detectors muon detectors, can measure content size simultaneously with high precision for rays in knee region. detector most powerful current ray observatory on ground.We made detailed comparison experimental simulated data. simulation does EPOS model.
