CMS High Level Trigger(HLT) performance in Run 3 / Maity, Dipak (Bhubaneswar, NISER) /CMS Collaboration
The CMS experiment at CERN operates a two-stage trigger system to efficiently filter and record events of potential physics interest. The system consists of a hardware-based Level 1 (L1) trigger, which processes detector data at 40 MHz using fast electronics such as FPGAs and ASICs, reducing the data rate to around 110 kHz. [...]

Search for a new pseudoscalar decaying into a pair of bottom and antibottom quarks in top-associated production in $\sqrt{s}$=13 TeV proton–proton collisions with the ATLAS detector
A search for a pseudoscalar $a$ produced in association with a top-quark pair, or in association with a single top quark plus a $W$ boson, with the pseudoscalar decaying into $b$-quarks ($a\rightarrow b\bar{b}$), is performed using the full Run 2 data sample using a dileptonic decay mode signature.

Measurement of the A dependence of the muon neutrino charged-current quasielastic-like cross section as a function of muon and proton kinematics at $<$E$_{\nu}>\sim$6 GeV / MINERvA Collaboration
The first simultaneous measurements of the $\nu_{\mu}$ quasielastic-like cross section on C, CH, H$_2$0, Fe, and Pb targets as a function of kinematic imbalance variables in the plane transverse to the incoming neutrino direction are presented. [...]

Searches for direct slepton production in the compressed-mass corridor in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector
This paper presents searches for the direct pair production of charged light-flavour sleptons, each decaying into a stable neutralino and an associated Standard Model lepton. [...]

Measurement of $W^+W^-$ production cross-section at 13.6 TeV with the CMS experiment / Phor, Saumya (Delhi U.) /CMS Collaboration
The first measurements of $W^{+}W^{-}$ production cross section in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The data used were recorded with the CMS detector at the LHC in 2022, corresponding to an integrated luminosity of 34.8 fb$^{-1}$. The events are selected by requiring one electron and one muon of opposite charge. The total inclusive $W^+W^-$ cross section is measured to be $125.7 \pm 5.6$~pb, consistent with the standard model predictions. Fiducial cross sections are also reported as a function of the jet multiplicity in the event and compared with different theoretical predictions..

Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a $W$ boson along with a muon or electron. [...]
