On the impact of dimension-eight SMEFT operators on Higgs measurements

Journal of High Energy Physics, 2019
Using the production of a Higgs boson in association with a W boson as a test case, we assess the impact of dimension-8 operators within the context of the Standard Model Effective Field Theory.

Time-dependent study of K S → π + π − decays for flavour physics measurements

Journal of High Energy Physics, 2021
Nowadays High Energy Physics experiments can accumulate unprecedented statistics of heavy flavour decays that allows to apply new methods, based on the study of very rare phenomena, which used to be just desperate.

A Theoretical Investigation on Coupled Mass‐charge Transport in a Binary Fluid

Advanced Theory and Simulations, EarlyView.
This study presents a theoretical framework for coupled mass‐charge transport in binary fluids using molecular dynamics simulations. By deriving governing equations from conservation laws and Onsager's theory, the approach introduces generalized diffusivity and electrostatic friction terms.

Tribological Design by Molecular Dynamics Simulation: Influence of the Molecular Structure on Wall Slip and Bulk Shear

Chemical Engineering &Technology, Volume 46, Issue 1, Page 95-101, January 2023., 2023
The bulk shear and wall slip of a confined nonpolar lubricant, a complex branched‐hydrocarbon oil, were studied using molecular dynamics simulation. Different temperatures and molecular masses were investigated for a Couette flow. As the number of branches of the liquid molecule increases, the shear stresses and the wall slip increase.

Entangling Higgs production associated with a single top and a top-quark pair in the presence of anomalous top-Yukawa coupling

Journal of High Energy Physics, 2017
The ATLAS and CMS collaborations observed a mild excess in the associated Higgs production with a top-quark pair t t ¯ h $$ \left(t\overline{t}h\right) $$ and reported the signal strengths of μ tth ATLAS  = 1.81 ± 0.80 and μ tth CMS  = 2.75 ± 0.99 based ...

Discovery of a New Phase in Thin Flakes of KV3Sb5 under Pressure

Advanced Science, EarlyView.
The discovery of an unexpected new phase is reported in thin flake of KV3Sb5 under pressure. The new phase, alongside the CDW and superconducting phases, reveals an intriguing interplay between various novel phases in the kagome system. These findings suggest that this phase is related to nematicity, showcasing the kagome system's potential for ...

Investigation of Magnetic Force Hysteresis in Electromechanical Actuators

Chemical Engineering &Technology, Volume 46, Issue 1, Page 158-166, January 2023., 2023
An approach for the phenomenological modeling of force hysteresis, which is characterized by a very simple parameterization and a relatively low error, is presented. The real‐time model considers the influence of hysteresis effects of the iron circuit, friction, variable stroke, and eddy currents on the generated force.

Measuring properties of a Heavy Higgs boson in the H→tt¯→bW+b¯W− $$ H\to t\overline{t}\to b{W}^{+}\overline{b}{W}^{-} $$ decay

Journal of High Energy Physics, 2018
Suppose a heavy neutral Higgs or scalar boson H is discovered at the LHC, it is important to investigate its couplings to the standard model particles as much as possible.

Shape‐Selective Molecular Separations Enabled by Rigid and Interconnected Confinements Engineered in Conjugated Microporous Polymer Membranes

Advanced Science, EarlyView.
Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.

Serendipity in dark photon searches

Journal of High Energy Physics, 2018
Searches for dark photons provide serendipitous discovery potential for other types of vector particles. We develop a framework for recasting dark photon searches to obtain constraints on more general theories, which includes a data-driven method for ...
