Ultralight vector dark matter search using data from the KAGRA O3GK run / LIGO Scientific Collaboration
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. [...]

Two-particle angular correlations of identified particles in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE / Ruggiano, Daniela (Warsaw U. of Tech.)
Two-particle angular correlation is one of the most powerful tools to study the mechanism of particle production in proton--proton (pp) collision systems by relating the difference between the azimuthal angle ($\Delta\varphi$) and the rapidity ($\Delta y$) of the particles from a pair. [...]

Search for prompt production of pentaquarks in open charm hadron final states / LHCb Collaboration
A search for hidden-charm pentaquark states decaying to a range of $\Sigma_{c}\bar{D}$ and $\Lambda_{c}^{+}\bar{D}$ final states, as well as doubly-charmed pentaquark states to $\Sigma_{c}D$ and $\Lambda_{c}^{+}D$, is made using samples of proton-proton collision data corresponding to an integrated luminosity of $5.7fb^{-1}$ recorded by the LHCb detector at $\sqrt{s} = 13 Te\kern -0.1em V$.

Probing EFT models using top quark production in multilepton final states / Basnet, Aashwin (Ohio State U.)
Using data consisting of top quarks produced with additional final leptons collected by the CMS detector at a center-of-mass energy of $\sqrt{s}=$13 TeV from 2016 to 2018 (138 fb$^{-1}$), a search for beyond standard model (BSM) physics is presented. [...]
