CP violation in three-body B decays: a model ansatz

open access: yesJournal of High Energy Physics, 2020
The mechanism of CP violation remains one of the puzzles in particle physics. Key to understanding this phenomenon are nonleptonic B decays, especially multibody decays which exhibit large CP asymmetries in various regions of phase space.

Conformal invariance and $2D$ statistical physics [PDF]

open access: yesBulletin of the American Mathematical Society, 2008
Summary: A number of two-dimensional models in statistical physics are conjectured to have scaling limits at criticality that are in some sense conformally invariant. In the last ten years, the rigorous understanding of such limits has increased significantly.

General coordinate invariance and conformal invariance in nonrelativistic physics: Unitary Fermi gas [PDF]

open access: yesAnnals of Physics, 2006
We show that the Lagrangian for interacting nonrelativistic particles can be coupled to an external gauge field and metric tensor in a way that exhibits a nonrelativistic version of general coordinate invariance. We explore the consequences of this invariance on the example of the degenerate Fermi gas at infinite scattering length, where conformal ...

Higgs boson pair production at NNLO in QCD including dimension 6 operators

open access: yesJournal of High Energy Physics, 2017
In this paper we present the computation of the Higgs boson pair production cross section, both inclusive as well as differential on the invariant mass distribution, at next-to-next-to-leading order (NNLO) in QCD including effects of new physics beyond ...

Higgs triplet extension of GRACE

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Much theoretical effort and automatization are required to confront new physics models with experimental data for many types of particle reactions at future colliders.

Some new invariant solutions of nonlinear fifth order partial differential equation via Lie approach

open access: yesPartial Differential Equations in Applied Mathematics
In this paper, the classical Lie symmetry analysis of (1+3) dimensional perturbed Zakharov–Kuznetsov (pZK) equation has been studied. We present a thorough classification of Lie point symmetries for pZK equation.

Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data collected by the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling

Apparent unitarity violation in high mass region of MbW from a “hidden” top partner at high energy colliders

open access: yesPhysics Letters B, 2016
Perturbative unitarity conditions have been playing an important role in estimating the energy scale of new physics, including the Higgs mass as the most important example.

New physics contributions to moments of inclusive b → c semileptonic decays

open access: yesJournal of High Energy Physics, 2023
Inclusive semileptonic B → X c ℓ ν ¯ ℓ $$ {X}_c\ell {\overline{\nu}}_{\ell } $$ decays, where ℓ = μ, e, are by now standard candles in the determination of the CKM element |V cb |. These determinations rely on the heavy-quark expansion and use moments of

High-dimensional and permutation invariant anomaly detection

open access: yesSciPost Physics
Methods for anomaly detection of new physics processes are often limited to low-dimensional spaces due to the difficulty of learning high-dimensional probability densities. Particularly at the constituent level, incorporating desirable properties such as
