It is known that there is huge hierarchy among the masses of quarks and leptons, and the lepton mixing is drastically different from quark mixing. The origin of fermion masses and flavor mixing is a longstanding puzzle of SM. Modular symmetry is a promising approach to address the flavor puzzle. This approach can overcome the drawbacks of traditional flavor symmetry, and it allows to explain...

Common lore suggests that effects of quantum gravity are difficult to unravel. The Planck scale is in fact about 14 orders of magnitude above the highest energy reached on Earth, namely at the Large Hadron Collider. In this talk, I will show that the quantum gravity cut-off can decrease in certain situations thus making quantum gravity effects accessible at energies lower than the Planck...

The LHCb experiment conducts a wide programme of measurements which indirectly probe physics beyond the standard model. Rare decays of beauty and charm quarks which proceed via flavour-changing neutral currents are particularly sensitive to new physics at the TeV scale and above. This talk will describe recent LHCb analyses of rare B and D meson decays to muons that have particular sensitivity...

In this talk, we focus on the TeV scale B−L extension of the Minimal Supersymmetric Standard Model (BLSSM), which naturally incorporates a seesaw mechanism for generating light neutrino masses. Our emphasis will be on exploring the various phenomenological implications of this class of models.

The anomalous magnetic moment of the muon is one of the most sensitive probes of physics at the weak scale. Its current measurement presents a 4.2 sigma deviations from the Standard Model prediction, what is an exciting hint of physics beyond the Standard Model. However, such a prediction is subject to theoretical and experimental uncertainties, coming mainly from the hadronic vacuum...

For those interested in connecting string theory to observational physics, the asymptotic limits of string theory moduli space represent one of the most interesting regions. This talk explores these limits from two distinct directions: first, surprising results concerning (integer) conformal dimensions in scenarios with moduli stabilised in these asymptotic regimes and second, the cosmology of...

In this talk I will consider the string theory axiverse in type IIB Calabi-Yau orientifold compactifications, and focus on the computation of axion photon couplings and hierarchies that arise in the many axion limit — i.e. at large values of $h^{1,1}$. In particular, I will discuss two distinct phenomena that hierarchically suppress axion photon interactions when the QED divisor is small: the...

I will attempt to review some recent directions in theoretical studies of dark matter candidates, underlying models, production mechanisms, etc., focusing primarily on WIMPs and axions. Next, I will discuss sensitivity of the ensuing properties of dark matter candidates on underlying assumptions and illustrate this with the case of axions produced in nonstandard cosmologies of the Big Bang.

Supersymmetry (with R-parity conservation) provides a natural dark matter candidate. In models with gravity mediated supersymmetry breaking, the discovery of the Higgs boson with mass 125 GeV and the lack of discovery of supersymmetric particles at the LHC heavily constrains this framework for dark matter. The current status will be reviewed. Supergravity may also play an important role in...

In addition to the supersymmetric vacua in 10 dimensions, heterotic-string theory gives rise to non-supersymmetric vacua that are in general contain physical tachyons in compactifications to 4 dimensions, which can be projected out by the GSO projections, and produce string amplitudes that are finite at one—loop. Over the past few years, in collaboration with Viktor Matyas and Ben Percival, we...

Modular transformations of string theory are shown to play a crucial role as discrete flavor symmetries of the Standard Model. They include CP transformations and provide a unification of CP and traditional flavor symmetries within the framework of the eclectic flavor scheme. The unified flavor group is non-universal in moduli space and exhibits the phenomenon of "Local Flavor Unification"...

Grand Unified Theories (GUTs) aim to unify all three fundamental interactions including electromagnetic, strong and weak interactions. A well-known phenomenological prediction of GUTs is proton decay, which sets a strong constraint to GUTs due to its null observation. On the other hand, masses and mixing of quarks and leptons are correlated since all fermions are arranged in the same...

Modified (the higher-derivative) supergravity models of cosmological inflation are introduced by extending the Starobinsky model of inflation to supergravity and including production of primordial black holes, in agreement with current precision measurements of the cosmic microwave background radiation. It leads to multi-field inflation, dark matter genesis as primordial black holes, and...

Particles that interact with the standard-model very weakly, or only gravitationally, may be created merely by the expansion of the universe. This mechanism may produce dark matter and be used to limit the properties of particles beyond the standard model.

High energy cosmic neutrinos are generated by the interactions of cosmic rays with matter & radiation, so their spectrum extends up to ZeV energies. The detection of cosmic neutrinos up to multi-PeV energies by the IceCube Neutrino Observatory at the South Pole has thus provided a novel laboratory for fundamental interactions, complementary to collider experiments. The measured cross-section &...

Motivated by the expected future progress in long-lived particle searches there has been a lot of activity recently from theorists studying models for LLPs. This talk concentrates on LLPs motivated by the observed smallness of neutrino masses. Examples are simple heavy neutral lepton models, motivated by different variants of the seesaw, or also supersymmetric models with R-parity violation....

Flavor has been traditionally seen as a problem for supersymmetric theories, "the flavor problem". Still, the Standard Model is not immune to this problem, also Yukawa couplings should be naturally O(1).
Flavor symmetries are used to explain the structure of Yukawa couplings and, simultaneously, of soft-breaking couplings in supersymmetric theories. In this scenario, SUSY can help to...

Higher symmetries in quantum field theory are novel concepts of symmetry that involve extended operators such as Wilson lines in gauge theory. We briefly review this formalism and then discuss recent applications to particle physics, including an organizing principle for unification models and instanton effects. Finally, we discuss how higher symmetry violation can lead to simple models of...

I will argue on the possibility that the smallness of some physical parameters signals a universe at a large distance corner in the string landscape of vacua. Such parameters can be the scales of dark energy and supersymmetry breaking, which should then be tied to a large `dark' dimension at the micron scale. I will discuss the theoretical framework and some of its main physical implications.

Dark Matter constitutes more that 80% of the total amount of matter in the Universe, yet almost nothing is known about its nature. A powerful investigation technique is that of searching for the products of annihilations of Dark Matter particles in the galactic halo (and beyond), on top of the ordinary cosmic rays.

In this talk, I will address precision predictions for the NMSSM Higgs sector as well as the...

The Weak Gravity Conjecture proposes that in any effective theory that can be consistently coupled to gravity, gravity must be the weakest force.

By studying M-theory on singular non-compact special holonomy spaces X we demonstrate, via a process of cutting and gluing of singularities that extend to the boundary of X, the appearance of 0-form, 1-form and 2-group symmetries in the resulting supersymmetric quantum field theory. We study the fate of these symmetries when these spaces become compact by employing sophisticated gluing...

Ten years of LHC Higgs data indicate that the properties of the observed Higgs boson are consistent (within the precision of the experimental data) with the predictions of the Standard Model (SM). Thus, any viable supersymmetric extension of the SM must incorporate a SM-like Higgs boson. This can be achieved either via the decoupling limit (where all additional Higgs scalars have masses...
