The recent results reported by the CMS collaboration, indicating"bumps"in the $gammagamma$ and $tautau$ channels at $m_phiapprox 95$ GeV, provide interesting hints for new physics. We find that the lightest Higgs state of the general 2HDM (2HDM Type-III) can perfectly and simultaneously accommodate the two excesses alongside with the LEP long-standing anomaly observed in the $bbar{b}$ channel while meeting all theoretical and experimental requirements. Furthermore, the study predicts an enhanced production process for the SM-like Higgs in $ppto tbar t H_{rm SM}$, offering a testable hypothesis for future experiments.
CMS合作最近报告的结果表明，在$m_phiapprox 95$ GeV时，$gammagamma$和$tautau$通道出现了 "凸起"，这为新物理学提供了有趣的暗示。我们发现，一般2HDM（2HDM Type-III）中最轻的希格斯态可以同时完美地容纳这两个过量，以及在$bbar{b}$通道观测到的LEP长期异常，同时满足所有的理论和实验要求。此外，研究还预言了$ppto tbar t H_{rm SM}$中类似SM的希格斯粒子的增强产生过程，为未来的实验提供了一个可检验的假设。

Precision luminosity measurements are essential to determine the fundamental properties of the physics processes at the LHC. The estimation of the integrated luminosity at the CMS experiment requires absolute scale calibration of the luminometers, which is derived under special LHC machine setup. Series of beam separation (van der Meer) scans are performed during these special runs. The transverse profile of the overlap between the proton beams are estimated by the continuous monitoring of the interaction rates together with the beam properties. The dominant sources of systematic calibration uncertainty are related to the precise estimation of the beam separation and the non-factorizability of the proton density distributions in the transverse direction. The correction factors and their uncertainties are extracted for each effect and propagated to determine the final absolute scale and the corresponding uncertainty. The obtained van der Meer scan calibration is applied to the full physics data-taking period in order to estimate the integrated luminosity. The latest results of the luminosity calibration studies are reported from the CMS experiment.

Measurements of flow coefficients and correlations between different types of particles are used to characterise the properties of the quark-gluon plasma created in heavy-ion collisions. Moreover, these precise measurements became a key observable in understanding the possible origin of the collective-like behaviour in small collision systems. Recent results of flow and correlations measurements of light and heavy hadrons, in pp, p-Pb, and Pb-Pb collisions are presented.
