I survey mechanisms that can guarantee a SM-like Higgs boson in the 2HDM without a fine tuning of parameters.

Discrete symmetries play a pivotal role in achieving an approximate Higgs alignment limit naturally. -
Dr Ferruccio Feruglio (University of Padova)Thursday
Symmetry principles have long been applied to the flavour puzzle. In a bottom-up approach, the variety of possible symmetry groups and symmetry breaking sectors is huge, the predictability is reduced and the number of allowed models diverges. A relatively well-motivated and more constrained framework is provided by supersymmetric theories where a discrete subgroup Γ of a non-compact Lie group...

B-$\bar{\rm B}$ mixing involves three observables, the mass

difference $\Delta m$ between the two neutral B eigenstates, their width
difference $\Delta \Gamma$, and the CP phase characterising CP violation
in mixing. The latter two quantities involve the off-diagonal element
$\Gamma_{12}$ of the 2$\times 2$ decay matrix $\Gamma$. I briefly
discuss possible insights into new physics to be... -

I will discuss a framework of natural inflation within supergravity dubbed `inflation by supersymmetry breaking’. The main idea is to identify the inflaton with the superpartner of the goldstino, in the presence of a gauged R-symmetry that may contain the R-parity of the supersymmetric Standard Model.

CP violation offers a powerful probe for testing the Standard Model. In this endeavour, non-leptonic decays of B mesons play a key role. I will discuss benchmark decays and puzzling patterns emerging from theoretical analyses of the current data.

Quantum mechanics is usually considered to be a theory based on indeterminism. Here we show that its mathematics actually suggests a completely deterministic underlying theory. This requires evolution operators that describe discretised jumps in space and time. To understand how the known elementary particles, arranged in the Standard Model, can be reconciled with this picture, the discrete...

In recent years spontaneous breaking of discrete time translation symmetry has become a fertile area of theoretical, experimental and computational research. New, dynamic states of matter have been discovered, that challenge traditional ideas about the nature of thermal equilibrium. I will give an overview of this work, and then suggest possible future directions and applications.

We will discuss the approach to the flavour problem

based on modular invariance.
In modular-invariant models of flavour,
hierarchical fermion mass matrices may arise
solely due to the proximity of the modulus $\tau$
to a point of residual symmetry.
This mechanism does not require flavon fields, and modular
weights are not analogous to Froggatt-Nielsen charges.
We show that hierarchies... -

The unprecedented collision energy of the LHC has opened up a new discovery frontier, however, without any signs of new physics in sight. The first LHC dedicated search experiment, MoEDAL, started data taking for Run-2. MoEDAL is designed to search highly ionising particle avatars of new physics using pp and heavy-ion collisions at the LHC. The planned upgrade for MoEDAL at Run-3 - the MAPP...

Dr Sander MooijWednesday
We review and generalise renormalisation methods in QFT in which no intermediate divergences show up. Moreover, in two-field models with a large mass hierarchy between the fields, the usual fine-tunings proportional to the large mass are absent. Therefore, in this formulation of perturbative QFT there is no naturalness problem at all: there is no influence from the "heavy" sector on the...

Prof. Sergey Ketov (Tokyo Metropolitan University and Kavli IPMU)Friday
The Starobinsky inflation and Higgs inflation in gravity, and their equivalence based on the common inflationary potential are extended to supergravity in the proper framework where the Starobinsky and Higgs descriptions of inflation arise in two different gauges of the same supergravity model.

Monica Pepe-Altarelli (CERN)Plenary
Flavour-changing neutral-current decays are loop-suppressed in the SM and are thus an ideal laboratory to look for contributions from new heavy particles and/or new interactions beyond the SM. At LHCb tensions are observed in measurements of branching fractions and angular observables for rare semileptonic decays, as well as in lepton flavour universality tests. I will review the current...

Rebeca Gonzalez Suarez (Uppsala University (SE))Thursday
With the LHC about to start its last data-taking period before being upgraded to the High-Luminosity LHC, it is time for the international high energy physics community to define the future of collider particle physics. The European Strategy for Particle Physics highlights an e+e- Higgs boson factory as the main priority and as a first step towards a very high-energy future hadron collider....

Direct detection experiments push the limits for WIMP dark matter, but they are also sensitive to many other ideas for new physics. The talk will cover implications for theory from limits of direct detection experiments and from the low E_R excess in XENON1T.
