Time reversal and CP invariance in Calabi-Yau compactifications [PDF]

open access: yesJournal of High Energy Physics, 2022
We revisit the question of time reversal and CP invariance in Calabi-Yau compactifications. We show that time reversal invariance is respected by quantum corrections to the prepotential.

One Antimatter— Two Possible Thermodynamics [PDF]

open access: yesEntropy, 2014
Conventional thermodynamics, which is formulated for our world populated by radiation and matter, can be extended to describe physical properties of antimatter in two mutually exclusive ways: CP-invariant or CPT-invariant.

Test of CP invariance in vector-boson fusion production of the Higgs boson using the Optimal Observable method in the ditau decay channel with the ATLAS detector. [PDF]

open access: yesEur Phys J C Part Fields, 2016
A test of CP invariance in Higgs boson production via vector-boson fusion using the method of the Optimal Observable is presented. The analysis exploits the decay mode of the Higgs boson into a pair of \documentclass[12pt]{minimal} \usepackage{amsmath ...

Sensitivity to CP discovery in the presence of Lorentz invariance-violating potential at T2HK/T2HKK [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The investigation of conservation/violation of conjugation and parity (CP) symmetry in the leptonic sector is essential to understanding the evolution of the universe. Lorentz invariance and CPT are fundamental symmetries of nature.

Test of CP invariance in vector-boson fusion production of the Higgs boson in the H → ττ channel in proton–proton collisions at s=13TeV with the ATLAS detector [PDF]

open access: yesPhysics Letters B, 2020
A test of CP invariance in Higgs boson production via vector-boson fusion is performed in the H→ττ decay channel. This test uses the Optimal Observable method and is carried out using 36.1fb−1 of s=13TeV proton–proton collision data collected by the ...

CP violation of quarks in A4 modular invariance

open access: yesPhysics Letters B, 2019
We discuss the quark mass matrices in the A4 modular symmetry, where the A4 triplet of Higgs is introduced for each up-quark and down-quark sectors, respectively.

$$A_4$$ A 4 modular invariance and the strong CP problem

open access: yesEuropean Physical Journal C: Particles and Fields
We present simple effective theory of quark masses, mixing and CP violation with level $$N=3$$ N = 3 ( $$A_4$$ A 4 ) modular symmetry, which provides solution to the strong CP problem without the need for an axion.

Investigating the effects of Lorentz Invariance Violation on the CP-sensitivities of the Deep Underground Neutrino Experiment [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The phenomena of neutrino oscillations offer a great potential for probing new-physics beyond the Standard Model. Any additional effects on neutrino oscillations can help understand the nature of the non-standard effects.

Solving the strong CP problem in string-inspired theories with modular invariance

open access: yesJournal of High Energy Physics
We show that solutions to the strong CP problem based on modular invariance can be extended to incorporate features that appear in string compactifications: quarks with mostly positive modular weights and non-trivial gauge kinetic functions.

Mass, Confinement and CP Invariance in the Seiberg-Witten Model" [PDF]

open access: yes, 1996
Several physics aspects of the Seiberg-Witten solution of N=2 supersymmetric Yang-Mills theory with SU(2) gauge group, supplemented with a small mass term for the "matter" fields which leads to an $N=1$ theory with confinement, are discussed.
