The leptonic future of the Higgs [PDF]

Journal of High Energy Physics, 2017
Precision study of electroweak symmetry breaking strongly motivates the construction of a lepton collider with center-of-mass energy of at least 240 GeV. Besides Higgsstrahlung ($e^+e^- \to hZ$), such a collider would measure weak boson pair production ($e^+e^- \to WW$) with an astonishing precision.

B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the NMSSM with the Flavour Expansion Theorem

Journal of High Energy Physics, 2019
In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference ΔM s(d), we perform a detailed study of B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the

CP asymmetry in the angular distribution of τ → KS πν τ decays

Journal of High Energy Physics, 2020
In this work, we study the C P asymmetry in the angular distribution of τ → K S πν τ decays, taking into account the known C P violation in K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ mixing. It is pointed out for the first time that, once the well-measured

CP Violations in Lepton Number Violation Processes and Neutrino Oscillations [PDF]

, 2000
We examine the constraints on the MNS lepton mixing matrix from the present and future experimental data of the neutrino oscillation and lepton number violation processes. We introduce a graphical representation of the CP violation phases which appear in

Extracting jet transport coefficient via single hadron and dihadron productions in high-energy heavy-ion collisions

European Physical Journal C: Particles and Fields, 2019
We study the suppressions of high transverse momentum single hadron and dihadron productions in high-energy heavy-ion collisions based on the framework of a next-to-leading-order perturbative QCD parton model combined with the higher-twist energy loss ...

The global geometrical property of jet events in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

New physics in the angular distribution of B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − (→ π − ν τ ) ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay

Journal of High Energy Physics, 2021
In B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay, the three-momentum p τ − $$ {\boldsymbol{p}}_{\tau^{-}} $$ cannot be determined accurately due to the decay products of τ − inevitably include an undetected ν τ ...
