SymbolFit: Automatic Parametric Modeling with Symbolic Regression / Tsoi, Ho Fung (UPenn, Philadelphia) ; Rankin, Dylan (UPenn, Philadelphia) ; Caillol, Cecile (CERN) ; Cranmer, Miles (Cambridge U. (main)) ; Dasu, Sridhara (U. Wisconsin, Madison (main)) ; Duarte, Javier (UC, San Diego (main)) ; Harris, Philip (MIT ; Harvard U. (main) ; IAIFI, Cambridge) ; Lipeles, Elliot (UPenn, Philadelphia) ; Loncar, Vladimir (MIT ; Belgrade, Inst. Phys.)
We introduce SymbolFit, a framework that automates parametric modeling by using symbolic regression to perform a machine-search for functions that fit the data, while simultaneously providing uncertainty estimates in a single run. [...]

Search for BSM Physics in High-Mass Diphoton Events at CMS / Kamble, Samadhan (Indian Inst. Tech., Madras) /CMS Collaboration
We present the results from an extensive search for BSM particles in `high-mass diphoton events', a distinctive phase-space indicative of various SM extensions such as Supersymmetry, extra dimensions, and non-minimal Higgs sectors. The searches for both spin-0 and spin-2 particles in resonant as well as non-resonant scenarios were carried out using the full luminosity of the LHC Run-II in proton-proton collisions at $\sqrt{s}$ = 13 TeV with the CMS detector. [...]

Higgs boson production cross section and couplings in the W boson pair decay channel in pp collisions at $\sqrt{s}= 13$ TeV with the CMS detector / Dash, Ganapati (Indian Inst. Tech., Madras) /CMS Collaboration
The production cross sections of the Standard Model Higgs boson decaying into a pair of W bosons have been measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced through gluon-gluon fusion, vector boson fusion, and in association with a vector boson. [...]

Rare $b \rightarrow sll$ decays at 13 $TeV$ by CMS Detector / Nayak, Samarendra (Bhubaneswar, NISER) /CMS Collaboration
Recent results on the rare $b \rightarrow sll$ decays are presented by the CMS experiment at 13 $TeV$. The individual branching fraction results of $B^{\pm} \rightarrow K^{\pm}\mu^{+}\mu^{-}$ and $B^{\pm} \rightarrow K^{\pm}e^{+}e^{-}$ decays are shown along with the lepton flavor universality (LFU).

Search for Supersymmetry in single lepton events and reinterpretation in the pMSSM-19 framework / Engelke, Frederic (Aachen, Tech. Hochsch.) /CMS Collaboration
Results are presented from a search for supersymmetry in events with a single electron or muon, and multiple hadronic jets. The data correspond to a sample of proton-proton collisions at $\sqrt{s}=13$ TeV with an integrated luminosity of $138 \ \text{fb}^{-1}$, recorded by the CMS experiment at the LHC. [...]

Measurement of the ttH production cross-section in multi-leptonic final states in pp collisions at a centre-of-mass energy of 13 TeV with the CMS detector / Ameen, Mohammad Mobassir (Indian Inst. Tech., Madras) /CMS Collaboration
The Yukawa coupling of the Higgs boson to the top quark is a pivotal parameter in the Standard Model, providing insights into fundamental particle interactions. This coupling is investigated through the production processes of Higgs bosons in association with top quarks, including tH and ttH. [...]

Recent results on heavy flavours and quarkonia from ALICE / Fionda, Fiorella (Cagliari U. ; INFN, Cagliari)
Heavy-flavour hadrons, containing at least one charm or beauty quark, are excellent probes of the deconfined medium created in ultra-relativistic heavy-ion collisions, known as quark-gluon plasma. [...]
