$t\bar{t}$ production in the forward region at LHCb / Vieites Diaz, M (Santiago de Compostela U.) /LHCb
Despite having an optimised design for b-physics, the LHCb spectrometer may beused as a general purpose detector in the forward region, covering thepseudorapidity $(η)$ range from 2 to 5. Its outstanding vertexing and particleidentification performances allow for an efficient tagging of heavy flavouredjets, and the separation of jets originating from $b$ and $c$ quarks. [...]

Search for heavy neutral lepton production in kaon decays / Parkinson, C J (Birmingham U.) /NA62
A search for heavy neutral lepton (HNL) production in charged kaon decays usinga data sample collected with a minimum bias trigger by the NA62 experiment atCERN in 2015 is reported. Upper limits are established on the elements of theextended neutrino mixing matrix for HNL mass in the range 170 − 448 MeV/$c^2$.This improves on the results from previous HNL production searches, setting morestringent limits and extending the mass range..

Studies of open charm production and properties at LHCb / O'Hanlon, Daniel (INFN, Bologna) /LHCb
Copious production of open-charm mesons and baryons at the LHC, in addition to the flexible trigger scheme, and excellent momentum resolution, impact-parameter, and particle identification capabilities of the LHCb detector, results in some of the most precise measurements to-date on the production and properties of open-charm hadrons. In particular, measurements of the $D_s^{+}$ meson production asymmetry at $\sqrt{s} = 7$ and $8$ TeV, and a high precision measurement of the $\Omega_c^0$ baryon lifetime, are presented. [...]

Testable leptogenesis scenarios and phenomenological implications / Lopez-Pavon, J (CERN)
The simplest extension of the Standard Model (SM) that can account for neutrinomasses consists in the addition of 2 right-handed neutrinos to the SM fieldcontent. In addition to the generation of the light neutrino mass and mixingpattern measured in neutrino oscillation experiments, the low scale realizationof the model provides an explanation for the matter-antimatter asymmetry of theUniverse via ARS leptogenesis, with right-handed neu-trino masses in the range[0.1-100] GeV.

The reactor neutrino anomaly: status and recent developments / Dentler, M (Mainz U.) ; Alvaro Hernandez-Cabezudo, A (KIT, Karlsruhe) ; Kopp, J (Mainz U. ; CERN) ; Machado, P (Fermilab) ; Maltoni, M (Madrid, IFT) ; Martinez-Soler, I (Madrid, IFT) ; Schwetz, T (KIT, Karlsruhe)
The observed antineutrino flux from nuclear reactors is consistently lower thanpredicted. This anomaly could hint at oscillations of active neutrinos into anew sterile neutrino species, or it could simply be a reflection ofunderestimated systematic uncertainties in the theoretical flux prediction.

Long lived particles and dark photons at LHCb / Borsato, M (Santiago de Compostela U.) /LHCb
The LHCb detector at the LHC is designed for indirect searches for physicsbeyond the Standard Model by the precise study of heavy hadron decays, but ithas a great potential also in direct searches of new light states below theelectroweak scale. Its excellent sensitivity has been recently demonstrated witha set of searches for light dimuon resonances (such as dark photons) and fordisplaced vertices due to particles with a significantly long lifetime..

Flavour anomalies and uv completion after the measurement of $R_{K*}$ / Nardecchia, Marco (CERN ; INFN, Trieste)
Since a few years (roughly from 2012-2013), a series of experimental results areshowing a coherent pattern of deviation from the Standard Model (SM) predictionsin semi-leptonic decays of the B-mesons. The so called " flavour anomalies " canbe grouped in two sets of observables: experimental deviations in semi-leptonicdecays in Flavour Changing Charged Current (FCCC) and experimental deviations insemi-leptonic decays in Flavour Changing Neutral Current (FCNC).

Gauged flavour symmetry for B anomalies / Alonso, Rodrigo (CERN)
Signs of physics beyond our stablished theory have sprung in the field ofB-meson physics. Although the evidence is not conclusive, theoreticalexploratory efforts help make sense of the new data in a consistent picture andallow contrast with other experimental searches. [...]

Measurements of CPV in beauty at LHC / Pardinas, J Garcia (Santiago de Compostela U.) /LHCb
Precision measurements of beauty hadron decays constitute excellent probes ofthe Standard Model and an important way to look for physics beyond. Inparticular, new sources of Charge-Parity violation are searched for, given theinconsistency between the matter/anti-matter asymmetry observed in the Universeand the small amount of Charge-Parity violation that the Standard Model canaccommodate.

Measurements of the Higgs boson decaying into two photons at CMS / Scott, Edward (Imperial Coll., London) /CMS Collaboration
The latest results of the Higgs boson decaying to two photons at the CMS experiment are presented. Measurements are based on the 35.9 $\textrm{fb}^{-1}$ 2016 dataset at a centre-of-mass energy of 13 TeV. [...]
