CMS Outer Tracker Module Production and Integration at NISER / Rahul Kumar Agrawal
In the LHC long shutdown 3, due to start in mid-2026, the LHC will be upgraded to the High-Luminosity LHC. To address the challenges for operation at the HL-LHC, such as an increased interaction rate and higher radiation levels, an upgrade of the tracking system of the CMS detector is being built. [...]

New physics searches in exotica sector at CMS experiment / Dhingra, Nitish (Panjab U.) /CMS Collaboration
The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) has a vast physics programme ranging from precision measurements of the Standard Model (SM) predictions to the new physics searches beyond the SM. This paper presents an overview of the research highlights from the CMS experiment using LHC Run 2 and Run 3 data to explore the exotica sector physics beyond the SM, including searches for long lived particles, heavy resonances, extra dimensions, quantum black holes, vector like quarks and leptons, and heavy neutral leptons.
