The antitrust laws are designed to prevent certain anti-competitive practices and to promote fair competition in the marketplace. Here's how you can find more detailed information on what these laws prohibit:

1. Research specific antitrust laws: There are several laws that fall under the umbrella of antitrust legislation, including the Sherman Act, the Clayton Act, and the Federal Trade Commission Act. You can find detailed information about these laws by searching for them individually.

2. Understand the key provisions: The key provisions of antitrust laws vary depending on the specific statute. Broadly, these laws prohibit practices such as monopolies, price fixing, bid rigging, tying arrangements, and unfair methods of competition.

3. Consult reliable sources: To gain a more comprehensive understanding, consult reputable sources such as government websites, legal databases, or textbooks on antitrust law. These sources should outline specific practices and behaviors that are considered anti-competitive and hence prohibited.

Remember that antitrust laws can be complex and their interpretation may vary depending on the jurisdiction and specific circumstances. For any legal concerns or advice, it is always recommended to consult a qualified attorney.
