I saw this symbol in the statement: 'Effective CP-violating angle θ≅
This is a Landau symbol. A quantity is called of order ##f(x)=\mathcal{O}(x^{n})## if
$$\lim_{x \rightarrow 0} \frac{f(x)}{x^n}=C=\text{const}.$$
In this somewhat abuse of notation it means that ##\theta/10^{-17}## is a value around 1.
(10-17). What does the highlighted symbol mean?
