If Rebecca decides to press charges against Samuel for slapping her, what could he be charged with?

The charge most applicable to the situation described, where Rebecca decides to press charges against Samuel for slapping her, is battery. Battery involves the intentional and unlawful use of force against another person that results in harmful or offensive contact. Since Rebecca was slapped, this physical act constitutes battery.

In this case, while assault is related, it typically refers to the threat or attempt to inflict harm, rather than the actual act of causing harm. Sexual assault pertains specifically to sexual offenses and is not relevant here, while harassment generally involves unwelcome or offensive conduct that does not necessarily result in physical contact. Thus, the nature of the act in question aligns directly with the definition of battery.
