Eung Jin Chun18/12/2023, 09:30Talk
In this talk, we discuss leptogenesis occurring at the time of the first order phase transition of U(1)_B-L breaking, dubbed as bubble assisted leptogenesis, in which the strong wash-out can be circumvented due to an efficient departure from equilibrium offered by the relativistic expansion of true phase bubbles. Taking carefully into account all the efficiency factors such as penetration...

Models incorporating moderately heavy dark matter (DM) typically need charged (scalar) fields to establish admissible relic densities. Since the DM freezes out at an early epoch, thermal corrections to the cross sections can be important. Here, we study the IR behaviour at finite temperatures, of dark matter annihilation cross sections, which potentially contains both both linear and...

We have explored the parameter space for the phenomenological minimal supersymmetric standard model (PMSSM) with specific focus on the region with a light neutralino dark matter (with mass less than half the mass of the Higgs), which is consistent with current collider and astrophysical constraints. We show that the latest results from the LHC searches for sparticles and direct detection...

We study the phenomenological signatures associated with a light fermiophobic Higgs boson within the type-I two-Higgs-doublet model at the HL-LHC. Our exhaustive parameter scan revealed a captivating mass range between 1 GeV and 10 GeV. This range retains a substantial number of viable parameter points, primarily due to the current experimental difficulties in probing soft decay products of...

The early Universe represents a unique laboratory for frontier physics, providing extreme conditions and amazing chances to test theoretical models. A large class of cosmological phenomena may allow us to probe particle physics at energy scales much beyond the reach of current and future colliders. Within this class, first order phase transitions cover a privileged role since they may leave...

In this talk, I will discuss different searches for neutrino mass models, particularly emphasizing the updates for LHC and prospect for HL-LHC. Special emphasize will be given on heavy neutral lepton candidates. I will also briefly touch upon the cosmological implications of few of the neutrino mass models.

In the standard cosmology, Dark Matter (DM) is generally assumed to be non-interacting. However, in several well-motivated particle physics models, which include a DM candidate, it participates in various interactions. In particular, we have considered interactions of DM

We analyse the cross-sections for each of the 2 $\to$ 2 scattering processes with the modified propagator(s) at the finite temperature in the dense fluid of a strongly interacting pion nucleon system ($\pi N$) that are observed in relativistic heavy ion collisions and neutron star mergers. We examine the shape profile of the resulting transport coefficients like shear viscosity, bulk...

The Large Hadron Collider (LHC) has already put very strong limits on the Beyond Standard Model particle masses. In most of the LHC searches, it is commonly assumed that these exotic particles are directly produced at the colliders or they decay directly to the Standard Model particles. But, theories such as the Pati Salam Model, Composite Higgs and Little Higgs scenarios suggest that the...

Light dark matter (DM) is getting increasingly more important in our quest to probe the dark sector physics. Direct detection of a sub-GeV scale dark matter is difficult as it lacks sufficient kinematic heft to have significant nuclear or electron recoil. In this regard, a boosted dark matter plays an interesting role. Before attempting to detect a boosted dark matter, we explore a possible...

The new muon $g-2$ measurement yields about $5.1$ sigma deviation from the

Standard Model (SM) prediction. Moreover, the measurement of the $W$ boson mass performed by the CDF experiment at the Tevatron shows a significant deviation not only from the SM value but also with the other precision measurements performed at LEP and LHC. In this work, we address these two discrepancies by extending... -

We discuss the possibility of generating the observed baryon asymmetry of the Universe by introducing a Majorana fermion coupled to quarks. We discuss decay and scattering processes. We explore the possibility of probing such a scenario using neutron-antineutron oscillation.

There is a long-standing anomaly in the ratio of the decay width for $\psi(3770)\to D^0\overline{D^0}$ to that for $\psi(3770)\to D^+D^-$ at the level of $9.5\,\sigma$. A similar anomaly exists for the ratio of $\phi(1020)\to K_\text{L}^0K_\text{S}^0$ to $\phi(1020)\to K^+K^-$ at $2.1\,\sigma$. In this study, we reassess the anomaly through the lens of Gaussian wave-packet formalism. Our...

The application of deep learning techniques to theoretical particle physics has recently witnessed explosive growth, opening up exciting new avenues for exploration. The integration of deep learning into theoretical particle physics is still in its early stages, but it holds immense potential for future breakthroughs. As these techniques continue to evolve and become more sophisticated, we can...

Left-right symmetric models fill in some of the lacunae in the Standard Model, such as providing an explanation for parity and neutrino masses. But the additional bosons in the theory must be heavy to avoid flavor-changing neutral currents, and the models lack a natural dark matter candidate. The Alternative Left-Right Model, emerging from E6 grand unification, is an attractive variation of...

In this talk, I will discuss an extension of the Standard Model (SM) with a complex scalar field, known as`flavon', based on the Froggatt-Nielsen mechanism. In an effective theory approach, the SM fermion masses and mixing patterns are generated in orders of the parameter related to the vacuum expectation value of the flavon field and the cut-off of the effective theory. By introducing...

Assuming a conformal phase of the early universe, we discuss the conformal backreaction, by studying the anomaly effective action around flat space and, in parallel, the anomaly induced actions (Fradkin Vilkovisly and Riegert's actions ) in curved space. Gravity is treated classically. Anomalies included take the form both of conformal (parity-even) and of chiral (parity odd)...
