# Two-Point String Amplitudes

## TL;DR

This paper demonstrates that the two-point tree level amplitude in flat space string theory simplifies to the standard free particle expression, clarifying its fundamental nature.

## Contribution

It establishes that the two-point amplitude in string theory matches the free particle form, providing a clearer understanding of basic scattering processes.

## Key findings

- Two-point amplitude equals free particle expression
- Simplifies understanding of string scattering at tree level
- Supports standard quantum field theory results in string context

## Abstract

We show that the two-point tree level amplitude in string theory in flat space is given by the standard free particle expression.
