“…In our previous research, we noticed that the violation phase could not be probed solely in the or process without interference from the background [29,30]. Conversely, in the process, violation could be probed solely through its kinematic angles [28,[31][32][33]. These may be clearly explained at the amplitude level after we obtain a compact formula.…”

“…At the Large Hadron Collider (LHC), the and processes are Higgs discovery channels [23,24], which have the advantage of a clean background and relatively large signal. They are also golden channels for the precise measurement of Higgs properties [25][26][27][28]. In our previous research, we noticed that the violation phase could not be probed solely in the or process without interference from the background [29,30].…”

“…Moreover, this means that interference between the -even term and -odd term exists at the differential cross section level after squaring the amplitude. Therefore, the interference can be probed through kinematic angles [28,[31][32][33]]. An obvious effect is a shift in the azimuthal angle caused by the interference between -even and -odd terms.…”

$CP$ violation may play an important role in Baryogenesis in early universe, and should be examined at colliders comprehensively. We study $CP$ properties of $HVV$ vertexes between Higgs and gauge boson pairs with defining a $CP$ violation phase angle $\xi$, which indicates the mixture of $CP$-even and $CP$-odd Higgs states in $HVV$ in new physics. A series of $HVV$ amplitudes $H\to\gamma\gamma, H\to\gamma V\to \gamma \ell\ell$, and $H\to VV\to 4\ell$ with $CP$ phase angle are studied systematically, which explains explicitly why $CP$ violation could only be probed in $4\ell$ process independently. We get a novel amplitude decomposition relation which illustrates if two preconditions (multilinear momentum dependent vertexes and current $J_\mu$ of $V\to \ell^+ \ell^-$ is vector-like) are satisfied, an high-point amplitude can be decomposed into a summation of a series of low-point amplitudes. As a practical example, the amplitude of $H\to\gamma V\to \gamma \ell\ell$, and $H\to VV\to 4\ell$ processes can be decomposed into summation of many $H\to\gamma\gamma$ amplitudes. Meanwhile, we calculate these amplitudes in the framework of on-shell scattering amplitude method, with considering both massless and massive vector gauge bosons with $CP$ violation phase angle. The above two approaches provides consistent results and exhibit clearly the $CP$ violation $\xi$ dependence in the amplitudes.

“…[7][8] Genetic manipulation of the central player in cellular response to hypoxia, known as hypoxia inducible factor 1α (HIF-1α), leads to profound changes in the skeletal system. [9][10][11][12] However, how hypoxic microenvironment initiates and directs osteogenesis and angiogenesis remains poorly understood. On one hand, hypoxia is critical for the initiation of repair and revascularization of the engineered tissue.…”

Tissue oxygenation is one of the key determining factors in bone repair and bone tissue engineering. Adequate tissue oxygenation is essential for survival and differentiation of the boneforming cells and ultimately the success of bone tissue regeneration. Two-photon phosphorescence lifetime microscopy (2PLM) has been successfully applied in the past to image oxygen distributions in tissue with high spatial resolution. However, delivery of phosphorescent probes into avascular compartments, such as those formed during early bone defect healing, poses significant problems. Here we report a multifunctional oxygen-reporting fibrous matrix fabricated through encapsulation of a hydrophilic oxygen-sensitive, two-photon excitable phosphorescent probe PtP-C343 in the core of fibers during coaxial electrospinning. The oxygen-sensitive fibers support bone marrow stromal cell (BMSC) growth and differentiation, while at the same time enable real-time high-resolution probing of partial pressures of oxygen (pO 2 ) via 2PLM. The hydrophilicity of the probe further facilitates its gradual release into the nearby microenvironment, allowing fibers to act as a vehicle for probe delivery into the healing tissue. In conjunction with a cranial defect window chamber model, which permits simultaneous imaging of the bone and neovasculature in vivo via two-photon laser scanning microscopy (2PLSM), the oxygen reporting fibers provide a useful tool for minimally invasive, high-resolution, real-time 3D mapping of tissue oxygenation during bone defect healing, facilitating studies aimed at understanding the healing process and advancing design of tissue engineered constructs for enhanced bone repair and regeneration.
