First results from FASER at the LHC / Hayakawa, Daiki (Chiba U.) /FASER Collaboration
The ForwArd Search ExpeRiment (FASER) is a new experiment at the Large Hadron Collider (LHC) designed to search for light, weakly-interacting particles. Placed 480 m downstream from the ATLAS interaction point along the beam collision axis, FASER detects particles that travel hundreds of meters. [...]

Multiplicity-dependent heavy flavour production at the LHCb experiment / Lane, Jake (Monash U.) /LHCb Collaboration
The LHCb experiment has obtained several interesting physics results from the $b$ and $c$ quark systems as a function of collision multiplicity. We show the measurement of the excited-to-ground state production ratio of charmonium ($c\bar{c}$) as a function of charged particle multiplicity in proton-proton ($pp$) collisions, the observation of strangeness enhancement from the ratio of $D_s^\pm$ to $D^\pm$ in $p\mathrm{Pb}$ collisions and finally observation of the modification of $b$ hadronisation from the ratio of $B_s^0$ to $B^0$ in $pp$ collisions. [...]

Combination of ATLAS and CMS searches for Higgs boson pair production at 13 TeV /CMS Collaboration
This note presents a combination of searches for Higgs boson pair (HH) production performed by the ATLAS and CMS Collaborations using proton-proton collision data sets recorded at $\sqrt{s}$ = 13 TeV at the LHC Run 2, corresponding to integrated luminosities ranging between 126 and 140 $\mathrm{fb^{-1}}$. The upper limit at the 95\% confidence level on the total HH production cross section corresponds to 2.5 times the standard model (SM) prediction with an expected value of 1.7 (2.8) assuming the absence (presence) of the SM HH signal.
