Astroparticle Physics Forum COSMOVIA

Maxim Yur'evich!
I looked through the text and have't found any corrections. Can you just say, what have You corrected?

After DAMA explanation I have put a sentence that it relates the signal to formation of anomalous isotopes of sodium. It is necessary for successive discussion of anomalous isotopes in DAMA detector matter.
When you recalculated numerical factors in Ch. 2 for S_2, you have also changed the value of the total mass within the cosmological horizon in the period of OHe creation. For the fixed OHe density the value of this mass, determined by the time of OHe formation is independent on the mass of OHe and thus should not change.

Dear Larisa,
Though your referat is accepted, where still remains a question, which I intend to ask you as an additional during exam.
Please check the numerical factor in the expression for T_od in Ch.2 with the use of the condition of OHe decoupling:
n_B \sigma v (m_p/m_o) t = 1
If you prepare the answer to this question, it would strongly facilitate our discussion at the exam.

Да, Максим Юрьевич, я согласна. Виновата. Когда я меняю S_2 на S_3, коэффициент в определении T_od уменьшается почти в 5 раз (с 200 до 43). Считая общую массу, получается, что за счет M_od я умножаю на 100, а за счет T_od делю на 5 в 3 степени. Поэтому порядок величины остается неизменным.

Dear Larisa,
My question is: can you check the value of T_od (and the numerical factor 43) with the use of the relationship
n_B \sigma v (m_p/m_o) t = 1
from which it was determined. Just put the expressions for n_B, \sigma, v, m_o and t and find T_od
