Dark matter and the early Universe: a review
/ Arbey, A. (IP2I, Lyon ; CERN ; IUF, Paris) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris)
Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter and its nature, and demonstrate the close interplay between the cosmological properties of the early Universe and the observables used to constrain dark matter models in the context of new physics beyond the Standard Model..

Semiautomated BSM model building procedures in MARTY1.1 through a 2HDM example
/ Uhlrich, G. (IP2I, Lyon) ; Mahmoudi, F. (IP2I, Lyon ; CERN) ; Arbey, A. (IP2I, Lyon ; CERN ; IUF, Paris)
MARTY is a C++ computer algebra system specialized for High Energy Physics that can calculate amplitudes, squared amplitudes and Wilson coefficients in a large variety of beyond the Standard Model scenarios up to the oneloop order. It is fully independent of any other framework and its main development guideline is generality, in order to be adapted easily to any type of model. [...]

The Schwarzian sector of higher spin CFTs
/ Datta, Shouvik (CERN)
Twodimensional conformal field theories with Virasoro symmetry generically contain a Schwarzian sector. This sector is related to the nearhorizon region of the nearextremal BTZ black hole in the holographic dual. [...]

Searching for New Physics with $B^{0} \to K^{*0} \mu^+ \mu^$
/ Neshatpour, S. (IP2I, Lyon) ; Hurth, T. (U. Mainz, PRISMA) ; Mahmoudi, F. (IP2I, Lyon ; CERN)
One of the main indications for New Physics in rare $B$decays is deduced from the tension between experimental and Standard Model predictions of the angular analysis of the $B^0 \to K^{*0} \mu^+\mu^$ decay. There are however possible nonlocal hadronic effects which in principle can also explain these tensions. [...]

Dark Matter, Destroyer of Worlds: Neutrino, Thermal, and Existential Signatures from Black Holes in the Sun and Earth

Dark matter can be captured by celestial objects and accumulate at their centers, forming a core of dark matter that can collapse to a small black hole, provided that the annihilation rate is small or zero. If the nascent black hole is big enough, it will grow to consume the star or planet. [...]

Searching for Lepton Flavour (Universality) Violation and Collider Signals from a SinglyCharged Scalar Singlet
/ Crivellin, Andreas (CERN ; Zurich U. ; PSI, Villigen) ; Kirk, Fiona (Zurich U. ; PSI, Villigen) ; Manzari, Claudio Andrea (Zurich U. ; PSI, Villigen) ; Panizzi, Luca (Uppsala U.)
In recent years, evidence for lepton flavour universality violation beyond the Standard Model has been accumulated. In this context, a singly charged $SU(2)_L$ singlet scalar ($\phi^\pm$) is very interesting, as it can only have flavour offdiagonal couplings to neutrinos and charged leptons, therefore necessarily violating lepton flavour (universality).

Deep inelastic scattering on the quarkgluon plasma
/ Cè, Marco (CERN) ; Harris, Tim (Milan Bicocca U. ; INFN, Milan Bicocca) ; Meyer, Harvey B. (Helmholtz Inst., Mainz ; Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Toniato, Arianna (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA)
We provide an interpretation of the structure functions of a thermal medium such as the quarkgluon plasma in terms of the scattering of an incoming electron on the medium via the exchange of a spacelike photon. We then focus on the deepinelastic scattering (DIS) regime, and formulate the corresponding moment sum rules obeyed by the structure functions. [...]

Top, Higgs, Diboson and Electroweak Fit to the Standard Model Effective Field Theory
/ Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Madigan, Maeve (Cambridge U., DAMTP) ; Mimasu, Ken (King's Coll. London) ; Sanz, Veronica (Valencia U., IFIC ; Sussex U.) ; You, Tevong (CERN ; Cambridge U., DAMTP ; Cambridge U.)
The search for effective field theory deformations of the Standard Model (SM) is a major goal of particle physics that can benefit from a global approach in the framework of the Standard Model Effective Field Theory (SMEFT). For the first time, we include LHC data on top production and differential distributions together with Higgs production and decay rates and Simplified Template CrossSection (STXS) measurements in a global fit, as well as precision electroweak and diboson measurements from LEP and the LHC, in a global analysis with SMEFT operators of dimension 6 included linearly.
